Storage of Chemicals

Proper storage of chemicals is a complex task due to the diverse physical properties of  numerous chemicals which may be present in the laboratory.  Chemicals must be segregated according to any manufacturer’s requirements as provided by the SDS or specified by the manufacturer’s label on the container.  Strict adherence to the following rules is a must when storing chemicals.

• All containers are to be properly labeled, in good condition, appropriate type and size for the material stored and must be tightly sealed.
• Incompatible chemicals will be stored separately by the hazard class such as but not limited to flammable liquids, organic acids, and oxidizers.
• Secure storage shelves and cabinets to prevent tipping and maintain appropriate aisles clear of obstructions.
• Storage spaces require properly maintained ventilation and adequate temperature control of the space environment.
• Do not store liquids above eye level.
• Flammable liquids exceeding four liters will be contained in an appropriate safety can and stored in vented flammable liquid storage cabinets where possible.
• Use only flammable proof refrigerators for storage of flammable liquids.
• Dispose of all peroxide forming material within 1 year of purchase or 6 months of opening.
• Food or food products purchased for human consumption will not be stored within the laboratory work area, refrigerated storage units, or storage area.
• The storage of highly reactive or corrosive liquids will require the installation of an appropriate containment system such as spill trays.
• High-pressure gas cylinders will be stored in well-ventilated areas secured by a cylinder clamp, chain or strap or base support.  Cylinders must be secured away from heat sources.
• Chemicals should be stored in secured areas preventing theft and should be locked when unattended.

Use of Chemicals

• Review container labels and SDS information for identification of the hazards associated with the material to be used.
• Review all laboratory standard operating procedures and laboratory protocols prior to chemical use.
• Review emergency procedures and ensure the required supplies and equipment for material release or spill are immediately available.
• Maintain knowledge of the locations of safety equipment including emergency showers, eyewash stations, fire extinguishers, fire blankets and first aid stations.
• Avoid working alone in laboratory facilities with hazardous chemicals.

• Wash hands and other exposed skin after working with hazardous chemicals.
• Do not leave potentially hazardous chemical processes unsupervised or unattended. 
• Conduct processes which may result in the release of toxic vapors, fumes, or dust within a fume hood or other adequate containment, or ventilation device.

Use of Nanomaterials

Although the health and safety concerns have not yet fully been investigated, it is recommended the following precautions be observed when handling nanomaterials:

• Any work involving nanomaterials must be included in the Laboratory’s Standard Operating Procedures (SOP’s).
• Observe standard laboratory safety procedures. Wear gloves (double nitrile is recommended), goggles, lab coats, appropriate clothing and shoes as specified under the Laboratory Safety Rules. To avoid wrist or forearm exposure, place the glove over the forearm sleeve.  Lab coats that become visibly soiled with nanomaterial should not be worn.
• Work that may cause the nanomaterial (either in solid or liquid form) to become airborne such as mixing, sonicating, weighing or agitating should always be done in a glovebox, biosafety cabinet or fume hood.  Fumes or vapors which may contain nanomaterials must be exhausted to a dedicated exhaust line or into a chemical fume hood.
• Nanomaterials must be maintained in sealed containers when the material is not in use or while being transported.
• Nanoparticles should always be handled as toxic substances and treated as hazardous waste.  See Hazardous Waste Management Manual for proper disposal.
• Never use solvents to clean up nanoparticles.  Only use amended water (water in which a surfactant has been added to increase absorption of contaminants) or cleaner compatible with the nanomaterial.
• Concerns over processes involving the use and manufacture of nanomaterials which may produce fire and/or explosion or using nanomaterials which have a high degree of reactivity should be addressed.
• Compressed gas cylinders containing gases which have a NFPA health rating of 3 or 4 or labeled with a GHS flammable pictogram, often used in the production of nanomaterials, must be used in a ventilated cabinet.
• Cleaning surfaces, equipment, or spills outside a fume hood will require the use of a half-face respirator (See Respiratory Protection for requirements) with P100 filters and appropriate gloves.  If cleaning has the potential to contaminate personal lab coats or clothing with a large amount of nanomaterial, disposable coveralls and booties must be worn.
• Any vacuuming of nanomaterials, including spills, must be done with a HEPA or high efficiency particulate air filtered vacuum.  Because of potential airborne nanoparticle generation during vacuuming, personnel must also use half-face respirators with P100 filters.

Use of Flammables/Combustibles

Materials that can generate sufficient vapors to ignite at temperatures below 100 degrees F (38 degrees C) are considered to be "flammable."  Materials that require temperatures above 100 degrees F (38 degrees C) for ignition are considered to be "combustibles."  Undetectable vapor trails from combustible sources can get into remote ignition sources, causing flashback fires.  A fire may also erupt between reactions of flammables, combustibles and oxidizers. The following precautions are to be observed when handling flammable or combustible materials.

• Open flames, smoking materials, hot surfaces, operation of electrical equipment, spark ignitors, or other similar ignition sources should be eliminated from areas in which flammable or combustible materials are used or stored.
• Minimal quantities of flammable/combustible material will be stored and used in lab areas.
• Liquid flammable material in excess of four liters will be stored in an approved safety can and stored in storage cabinets within designated chemical storage areas which are designed and labeled for the purpose of storing flammable materials.
• Flammable liquids stored in glass containers shall not exceed four liters unless the chemical purity must be protected and the storage is authorized by the Laboratory  Supervisor.
• Refrigerators and freezers used for storage of flammable or combustible materials must be flammable proof units designed and labeled for this purpose.
• When transferring or dispensing flammable liquids from large drums ensure drums are properly grounded and bonded. Ensure areas used for storage of flammable and combustible materials are provided with adequate fire detection/fire suppression systems.

Use of Corrosives

Corrosive materials produce destruction of living tissues at the site of wherever the skin may come in contact with the material. Corrosive materials may come in the form of a solid, liquid or a gas.  When handling materials considered chemically reactive at the point of contact and capable of causing damage to human tissue, the following procedures should be observed.

• Depending on the work performed, face shields, gloves, rubber aprons, eye protection or boots may be required.
• Always add acid to water (never water to acid) to prevent or avoid violent reactions or splattering of the substance.
• In the event of eye or skin contact with corrosives, immediately flush the area of contact with water for a period of 15 to 20 minutes, remove contaminated clothing, and seek medical assistance. Report all accidents to the Lab Supervisor.  Eyewashes and showers should be located within 10 seconds travel time from work area.
• Neutralizing agents appropriate and adequate amount for spill cleanup.
• Oxidizing acids (nitric, perchloric and chromic) should be segregated from all other materials.  
• Organic and inorganic acids should be stored separately.
• Acids and bases should be stored separately.
• Calcium gluconate gel must be readily available wherever hydrofluoric acid is used. Medical treatment must be sought immediately when exposed to hydrofluoric acid.
• Polyethylene glycol (PEG 300) must be readily available if phenol is being used.  PEG 300 is used in case of exposure to phenol.  If exposed to phenol, immediate medical treatment is required.
• Use of perchloric acid may result in formation of explosive perchloric acid salts.  Perchloric acid must only be used in approved perchloric acid hoods.

Use of Reactives

Chemicals which react rapidly with themselves or other materials often produce a violent release of energy similar to a detonation.  Extreme care and caution must be exercised when working with the following materials

• Pyrophorics ignite spontaneously with air.
  • Examples include metal alkalis, phosphorous, fine powders of metal such as magnesium, aluminum, and zinc.
  • Use or store in a safe, inert environment.
  • Avoid using near solvents that are flammable
  • Residues should be deactivated according to the laboratory’s standard operating procedure prior to disposing of the empty container.
• Oxidizers react violently with organic material. 
  • Examples include perchloric, chromic, and fuming nitric acids, sodium and ammonium nitrates and hydrogen peroxides.
  • Use minimum amounts and store away from organic material, flammables and reducers.
  • Store in secondary containment away from other chemicals.
  • Oxidizers used in organic reactions should be completely spent/deactivated prior to placing in sealed containers.
  • Deactivate residues according to the standard operating procedure of the laboratory prior to discarding the empty container.
• Organic peroxides may react with organic material resulting in fires or explosions.  They are highly flammable and extremely sensitive to heat, friction, impact, light, and strong oxidizing and reducing agents.
  • Examples include  benzoyl peroxide, butyl peroxide, and lauroyl peroxide
  • Date all peroxidizables when received and when opened for use, disposal of material within six months of  opening or twelve months of purchase. If it is desired to keep the container longer than this, a peroxide test must be performed. Never open a container a container with obvious crystal formations around the lid.
  • Never use near chemicals and materials such as paper and wood.
  • Observe all manufacturer’s use and storage instructions.  Refrigeration and/or hydration may be required.
  • Do not attempt to concentrate organic peroxides (e.g., distillation, extraction or crystallization.)
• Peroxide Forming Material react with oxygen to form peroxides. Impact, heat or friction can cause peroxide explosions.
  • Examples include ethyl ether, tetrahydrofuran, isopropyl ether and potassium metal.
  • Container should be labeled as to date received, open and when last tested for peroxides.
  • Dispose of chemical on or prior to expiration date on the container.  To retain the chemical beyond this date the container must be tested for peroxide forming chemicals.
  • Containers that are deformed or have crystal formation on them should never be handled.  Contact EH&S for proper disposal.
• Water reactives combine with water to spontaneously ignite or produce flammable or toxic gases.
  • Examples include alkali metals such as lithium, sodium, potassium, acid anhydrides and acid chlorides.
  • Avoid contact and handle away from water.
  • Use dry sand to smother fire.
  • Provide ventilation to disperse flammable gases.
  • Residues should be deactivated according to the laboratory’s standard operating procedure prior to discarding the containers.

Use of Carcinogens/Toxins

• RESOURCES:
  • OSHA listed carcinogens
  • 15th RoC on Carcinogens: Substances Known to be Carcinogens and as Reasonably Anticipated to be Carcinogens.  These chemicals require similar handling procedures, but require more judgment for use and handling such as duration of use, amount of material used, conditions of use, formulations being used, and requires the authorization to use by a Lab Supervisor
  • International Agency for Research on Cancer. (IARC) Carcinogenic to Humans.
  • Carcinogens, Reproductive Toxins and Teratogens.
  • Environmental Protection Agency (EPA) Appendix A to 40CFR355-Emergency Planning and Notification List of Extremely Hazardous Substances (Scroll down to Appendix A)

Biohazardous Materials

Biohazardous materials are those materials that may cause harm to humans, domestic or wild animals or plants. The University Biosafety Manual discusses rules and guidelines for the safe use, containment and safe disposal of biohazardous material.

Laser Safety

Class IIIB lasers are visible, ultraviolet, and infrared lasers that produce eye injuries instantly form both direct and specular reflected beams. Class IV lasers present all of the hazards of Class III lasers and may also produce eye or skin damage from diffuse scattered light. Training and safety requirements for personnel who will be using lasers can be found in the Laser Safety Program.

Radiation Safety

As the use of radiation emitting materials and devices has grown, so has our understanding of the potential hazards associated with their use. Concerns over the potential hazards and associated risks have led to recommendations governing the exposure limits and ultimately to strict regulatory controls governing the possession and use of all sources of ionizing radiation. The University Radiation Safety Manual contains information and procedures that must be understood and followed in order to ensure all uses of ionizing radiation at the University of Northern Iowa meet regulatory compliance and resultant radiation exposures are maintained “As Low as Reasonably Achievable (ALARA)”.

Disposal of Hazardous Waste Material

Many materials that are generated in the laboratory are often considered hazardous waste and must be handled and disposed of accordingly. The University of Northern Iowa Environmental Health and Safety Office has generated a Hazardous Waste Management Manual that not only describes this material but also how to properly dispose of a number of different types of hazardous materials.

Physical Hazards

Among the most common injuries in the laboratory are burns, cuts, slips and trips, electrical shock, noise, mechanical, etc. Minimums safe practices should include the following:

• Use extreme caution around hot plates, heating mantles, burners, ovens, furnaces, etc.

ENGINEERING CONTROLS

Engineering controls are physical measures that can reduce or eliminate the hazards associated with the use of hazardous chemicals to whatever extent possible through the substitution of less hazardous equipment, chemical, or processes, isolation of the operator or process, establishing local and general exhaust or ventilation.

Laboratory Fume Hoods

Laboratory fume hoods are intended to keep chemical vapors from escaping into the laboratory. The hood serves as the primary means for respiratory protection of laboratory personnel with physical isolation and containment of chemicals.  A fume hood will be utilized for chemical procedures that have the potential for the following:

• Airborne concentrations of one or more chemicals approaching the corresponding. Permissible Exposure Limit (PEL).
• Flammable vapors approaching one tenth of the lower explosion limit.
• Materials of unknown toxicity.
• Odors which are potentially annoying to other personnel.

Procedures Considered to be Acceptable to Conduct Outside of the Fume Hood System

• Water-based solutions of inorganic salts, dilute acids, bases, or other reagents.
• Very low volatility liquids or solids.
• Closed systems that will prevent a significant escape to the laboratory environment.
• Extremely small quantities of material that might otherwise be considered hazardous. 

Administrative Controls

Administrative controls are procedural measures that can be taken to reduce or eliminate hazards associated with the use of hazardous chemicals.

• Assign a Departmental Chemical Hygiene/Safety Officer in each department.
• Ensure personnel in charge of laboratories understand their responsibilities under the Laboratory and Studio Chemical Safety Plan.
• Observe all standard operating practices and procedures for chemical safety, good hygiene, and good housekeeping.
• Ensure employees are provided with adequate training to work safely with hazardous chemicals/materials.
• Prior approval, authorization of the department head or designated representative is required for particular hazardous operations, procedures, or activities.
• Restrict access to areas where hazardous chemicals or material is used or stored.
• Designate and post signs or placards to identify hazardous areas.
• Label hazardous material according to university container labeling procedures.
• Hazardous waste must be managed using university approved procedures according to the University Hazardous Waste Management Manual.
• Post the entrance to laboratory areas where chemicals are used or stored in the following manner:  Emergency information including name and phone number responsible party to contact in the event of fire, accident, or spill.
• Identify specific types of hazards such as flammable, radiological, biological with standard signs.

• Chemical containers will be labeled according the standards identified in the University Hazard Communication Program.
• Radioactive materials must be managed using University approved procedures according to the University Radiation Safety Manual.

Control Measures

Personal protective equipment is personal apparel which is typically provided and maintained by the employer, compatible with the required degree of protection from chemicals or hazards.  Apparel includes, but not limited to head protection; safety glasses, goggles; aprons, gloves, lab coats; respirators; hearing protection; welding helmets; shoe protection.  The Department Head or designee is responsible for the coordination and oversight for the use of personal protective equipment in laboratory facilities.

Respiratory Protection

When engineering controls cannot effectively control hazardous chemical contaminants within the work area, personnel will be required to wear respirator protective equipment. Personnel designated to use respiratory equipment must have proper medical exams, must be properly fit and trained for the proper use of a respirator as provided for in the written Departmental Respiratory Program and the regulations identified in 29CFR1910.134.

Eye and Face Protection

Eye and face protection is required where there is reasonable probability for eye or face injury.  Eye and face protective equipment will meet or exceed the standards set forth by ANZI Z87.1 and by OSHA regulations. Shields are to protect the face from possible splash but will not prevent a splash from the side.  Eye protection must be worn in conjunction with safety shields.

Hand and Body Protection

Specific precautions must be taken to prevent significant exposure to hazardous chemicals through contact with the skin. Appropriate protection should be selected to meet the needs of the specific hazardous environment.

• Lab coats will be worn by personnel in any area where chemicals are routinely used or stored.  Apparel will be laundered frequently and removed immediately if contaminated with hazardous chemicals/materials.
• Gloves will be required when there is, but not limited to, the potential for contact with corrosive or toxic materials.  Gloves will be selected to meet the needs of the hazards.  Gloves will be properly maintained and inspected for wear and effectiveness of protection.
• Required protective apparel and equipment will be selected to meet the needs of the hazardous chemical operation or hazards in the work area and provided by the university at the discretion of the department head or designated representative.
• Bare feet, sandals, and other open toed shoes are not permitted in chemical laboratories or other hazardous areas.  The requirement and need for safety shoes in chemical laboratories can be made after careful review of the hazards by the Lab Supervisor with the authorization of the Department Head.

Safety Shields/Containment

• Fume hoods with drawn sashes, glove boxes, face shields, or other protective devices will be utilized whenever procedures with a high potential for sudden release or splattering is involved.  Chemicals which react explosively require special safety shields and/or containment.  Fume hoods or other similar devices will be properly maintained and inspected on a regular schedule.
• Drench type safety showers shall be easily accessible, available within 100 feet or 10 seconds travel time of each area where corrosive or flammable liquids are used or stored, properly maintained and inspected for adequate operation.
• Eye wash fountains will be accessible in all areas where corrosives, hot liquids, or other irritating hazardous chemicals/materials are used or stored.  Eye wash fountains will be properly maintained and inspected on a regular schedule for adequate operation.
• Fire extinguishers will be accessible, match the fire hazards in the area, tested and inspected according to applicable regulations, and contain either carbon dioxide or dry chemical extinguishing agent.
• First aid stations will be provided and maintained with the appropriate supplies for the hazards in the work area.  Employees will receive specific information and training for the proper use of all first aid material provided in the first aid station.
• Fire blankets, when provided in hazardous work areas, will not contain asbestos material and will be properly inspected on an annual schedule to ensure their presence and generally acceptable condition as a fire suppression device.
• Flammables requiring refrigeration will not be stored in domestic refrigerators.  The light switch and thermostat could ignite the flammable vapors causing an explosion.  Flammables will be stored in either explosion proof or flammable material storage refrigerator.

Laboratory Maintenance/Assessment

General laboratory chemical safety will be maintained with an effective assessment program developed and completed by the departmental Chemical Hygiene Officer in conjunction with the individual Lab Supervisor.  The documentation and record keeping task associated with an inspection and testing program must be maintained by each Lab Supervisor.  Documentation and records must be readily available in the event of an unannounced OSHA inspection.  Assessments will consist of a formal review of chemical and general safe practices of the lab, housekeeping, and include maintenance checks of safety related equipment.  Requirements of the inspections include:

• Chemical, general safety practices and housekeeping should be completed quarterly.  (See Appendix A for Inspection checklist.)

Appendix A

• Eye wash fountains are to be activated weekly.  Assessments of emergency showers will be conducted on an annual basis by a representative of the Environmental Health and Safety Office.  Respiratory maintenance will be completed according to procedures and schedule in the Departmental Respirator Program.
• Fume hood assessments will be completed annually by a representative of the Environmental Health and Safety Office.

• Location and availability of reference material including SDS information, Merck index, or Biosafety in Microbiological and Biomedical Laboratories regarding the hazards and safe practices for working in the laboratory
• Procedures for responding to emergencies (fire, chemical spill, severe weather, etc.) as written in the laboratory’s Emergency Action Plan.  
• Permissible exposure limits of OSHA regulated substances or recommended limits imposed by the material’s manufacturer or distributor that are not OSHA regulated. 
• Type and level of hazards to which the employee are exposed.
• Safe usage and emergency handling procedures for hazardous chemicals in their work/lab area.
• Methods or procedures to detect the presence or release of hazardous chemicals, biological and radioactive materials. 
• Signs and symptoms associated with laboratory chemical exposure.
• Physical and health hazards associated with chemicals in the work area.
• Measures employees can take to protect themselves from hazards including use of standard operating procedures, control measures, personal protective equipment, and emergency procedures.
• Proper waste disposal procedures.
• Proper record keeping including inventories of chemical, biological and radioactive material.
• Employees receiving training must sign an appropriate log documenting their attendance of the training event.  
• Each Lab Supervisor will maintain an outline of the training provided and the attendance log.  These records must be readily available in the event of an unannounced OSHA inspection.

EXPOSURE ASSESSMENT/MEDICAL EXAMINATION/EVALUATION

Procedures to follow if suspected overexposure of employees to hazardous chemicals:

Suspected Overexposure Results to IDLH

• Call University Public Safety at (319 (27)3-2712or 9-911 to report the incident. 
• The victim will be transported via ambulance to Sartori Memorial Hospital located at 515 College Street, Cedar Falls. 
• The victim should be accompanied by the SDS (Safety Data Sheet) of the respective chemical/material they were exposed to.

Suspected Overexposure Does Not Result in IDLH

• Exposed person will follow the normal reporting procedure for their respective department.
• Employee exposure to a hazardous chemical/material must be assessed through monitoring if there is reason to believe that an overexposure has occurred. 
• If employee is referred to the designated University Occupational Health Provider (Arrowhead Clinic), a copy of the SDS sheet of the chemical/material that they were exposed to will be taken to the appointment.

LABORATORY HOOD SYSTEMS

Laboratory hoods are designed to protect laboratory personnel by capturing or containing chemical and radiological contaminants by preventing their escape into the laboratory environment.  Refer to the University Fume Hood Program for additional information.

SAFETY DATA SHEETS

Copies of Safety Data Sheets (SDS) must be maintained for every hazardous chemical within the department and must be placed on the University Chemical and Safety Data Sheet Database.  All students and faculty should review the SDS sheet for chemicals they may come in contact with in the laboratory in which they will be working prior to using them.
