Color coding system on slide in Section 7 Handling/Storage


Hazards Identification: Hazards Identification Potential Health Effects ---------------------------------- The perception of formaldehyde by odor and eye irritation becomes less sensitive with time as one adapts to formaldehyde. This can lead to overexposure if a worker is relying on formaldehyde's warning properties to alert him or her to the potential for exposure. Inhalation: May cause sore throat, coughing, and shortness of breath. Causes irritation and sensitization of the respiratory tract. Concentrations of 25 to 30 ppm cause severe respiratory tract injury leading to pulmonary edema and pneumonitis. May be fatal in high concentrations. Important information to know signs and symptoms of overexposure


Hazards Identification: Hazards Identification Skin Contact: Toxic. May cause irritation to skin with redness, pain, and possibly burns. Skin absorption may occur with symptoms paralleling those from ingestion. Formaldehyde is a severe skin irritant and sensitizer. Contact causes white discoloration, smarting, cracking and scaling. Eye Contact: Vapors cause irritation to the eyes with redness, pain, and blurred vision. Higher concentrations or splashes may cause irreversible eye damage. Important information to know signs and symptoms of overexposure


Hazards Identification: Hazards Identification Chronic Exposure: Frequent or prolonged exposure to formaldehyde may cause hypersensitivity leading to contact dermatitis. Repeated or prolonged skin contact with formaldehyde may cause an allergic reaction in some people. Vision impairment and enlargement of liver may occur from methanol component. Formaldehyde is a suspected carcinogen (positive animal inhalation studies). Aggravation of Pre-existing Conditions: Persons with pre-existing skin disorders or eye problems, or impaired liver, kidney or respiratory function may be more susceptible to the effects of the substance. Previously exposed persons may have an allergic reaction to future exposures. You should know both acute and chronic health effects


First Aid Measures: First Aid Measures 4. First Aid Measures Inhalation: Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Call a physician. Ingestion: If swallowed and the victim is conscious, dilute, inactivate, or absorb the ingested formaldehyde by giving milk, activated charcoal, or water. Any organic material will inactivate formaldehyde. Keep affected person warm and at rest. Get medical attention immediately. If vomiting occurs, keep head lower than hips. Skin Contact: In case of contact, immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. Thoroughly clean shoes before reuse. Get medical attention immediately. Eye Contact: Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper eyelids occasionally. Get medical attention immediately. Note to Physician: Monitor arterial blood gases and methanol levels after significant ingestion. Hemodyalysis may be effective in formaldehyde removal. Use formic acid in urine and formaldehyde in blood or expired air as diagnostic tests.


Fire Fighting Measures: Fire Fighting Measures 5. Fire Fighting Measures Fire: Flash point: 60C (140F) CC Autoignition temperature: 300C (572F) Flammable limits in air % by volume: lel: 7.0; uel: 73 Flammable liquid and vapor! Gas vaporizes readily from solution and is flammable in air. Explosion: Above flash point, vapor-air mixtures are explosive within flammable limits noted above. Containers may explode when involved in a fire. Fire Extinguishing Media: Water spray, dry chemical, alcohol foam, or carbon dioxide. Special Information: In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full face piece operated in the pressure demand or other positive pressure mode. Water may be used to flush spills away from exposures and to dilute spills to non-flammable mixtures.


Accidental Release Measures: Accidental Release Measures 6. Accidental Release Measures Ventilate area of leak or spill. Remove all sources of ignition. Wear appropriate personal protective equipment as specified in Section 8. Isolate hazard area. Keep unnecessary and unprotected personnel from entering. Contain and recover liquid when possible. Use non-sparking tools and equipment. Collect liquid in an appropriate container or absorb with an inert material (e. g., vermiculite, dry sand, earth), and place in a chemical waste container. Do not use combustible materials, such as saw dust. Do not flush to sewer! US Regulations (CERCLA) require reporting spills and releases to soil, water and air in excess of reportable quantities. The toll free number for the US Coast Guard National Response Center is (800) 424-8802. If a leak or spill has not ignited, use water spray to disperse the vapors, to protect personnel attempting to stop leak, and to flush spills away from exposures.


Handling/ Storage: Handling/ Storage 7. Handling and Storage Store in a tightly closed container. Protect against physical damage. Store in a cool, dry well-ventilated location, away from any area where the fire hazard may be acute. Outside or detached storage is preferred. Separate from incompatibles. Containers should be bonded and grounded for transfers to avoid static sparks. Storage and use areas should be No Smoking areas. Use non-sparking type tools and equipment, including explosion proof ventilation. Wear special protective equipment (Sec. 8) for maintenance break-in or where exposures may exceed established exposure levels. Wash hands, face, forearms and neck when exiting restricted areas. Shower, dispose of outer clothing, change to clean garments at the end of the day. Avoid cross-contamination of street clothes. Wash hands before eating and do not eat, drink, or smoke in workplace. Protect from freezing. Containers of this material may be hazardous when empty since they retain product residues (vapors, liquid); observe all warnings and precautions listed for the product.


Exposure Controls/ Personal Protection: Exposure Controls/ Personal Protection 8. Exposure Controls/Personal Protection Airborne Exposure Limits: -OSHA Permissible Exposure Limit (PEL): 0.75 ppm (TWA), 2 ppm (STEL), 0.5 ppm (TWA) action level for formaldehyde 200 ppm (TWA) for methanol -ACGIH Threshold Limit Value (TLV): 0.3 ppm Ceiling formaldehyde, Sensitizer, A2 Suspected Human Carcinogen 200 ppm (TWA) 250 ppm (STEL) skin for methanol OSHA PEL is what is required by law. ACGIH services as good guidance If you suspect you are exceeding either of these levels call Sheila Simmons at 474-6771 for an evaluation


Exposure Controls/ Personal Protection: Exposure Controls/ Personal Protection Ventilation System: A system of local and/or general exhaust is recommended to keep employee exposures below the Airborne Exposure Limits. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area. Please refer to the ACGIH document, Industrial Ventilation, A Manual of Recommended Practices, most recent edition, for details. Will most likely be a lab hood


Exposure Controls/ Personal Protection: Exposure Controls/ Personal Protection Personal Respirators (NIOSH Approved): If the exposure limit is exceeded and engineering controls are not feasible, a full facepiece respirator with a formaldehyde cartridge may be worn up to 50 times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest. For emergencies or instances where the exposure levels are not known, use a full-facepiece positive-pressure, air-supplied respirator. WARNING: Air purifying respirators do not protect workers in oxygen-deficient atmospheres. Irritation also provides warning. For Methanol: If the exposure limit is exceeded and engineering controls are not feasible, wear a supplied air, full-facepiece respirator, airlined hood, or full-facepiece self-contained breathing apparatus. Breathing air quality must meet the requirements of the OSHA respiratory protection standard (29CFR1910.134). Where respirators are required, you must have a written program covering the basic requirements in the OSHA respirator standard. These include training, fit testing, medical approval, cleaning, maintenance, cartridge change schedules, etc. See 29CFR1910.134 for details.


Respiratory Protection: Respiratory Protection Respirators Employees who wear respirators also need a medical evaluation, fit testing, and training (whether it is elective or required use).


Exposure Controls/ Personal Protection: Exposure Controls/ Personal Protection Skin Protection: Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls, as appropriate, to prevent skin contact. Eye Protection: Use chemical safety goggles and/or a full face shield where splashing is possible. Maintain eye wash fountain and quick-drench facilities in work area.


Exposure Controls/ Personal Protection: Exposure Controls/ Personal Protection Other Control Measures: See OSHA Standard for more information on personal protective equipment, engineering and work practice controls, medical surveillance, record keeping, and reporting requirements.

Flammables: Flammables When handling flammable materials… Limit quantities stored according to Appendix 9 of the CHP Do not handle around ignition sources. Never heat by using an open flame. Instead use steam baths, water baths, oil baths, heating mantles, and hot air baths. Do not transfer Class I (highly flammable liquids) (Appendix 9) from one vessel to another in any exit passageway. Transfer flammable liquids from 5 gallon containers (or less) to smaller containers in a laboratory fume hood or an approved flammable liquid storage room.


Materials That Use the Explosive Symbol : Materials That Use the Explosive Symbol 1. Explosives 2. Water Reactives 3. Unstable Reactives


Materials That Use the Flaming "O" Symbol: Materials That Use the Flaming "O" Symbol 1. Oxidizers cause other substances to burn more easily through a chemical reaction or change. 2. Organic Peroxides contain oxygen and act as powerful oxidizers.


“Reactive” Chemicals: “Reactive” Chemicals Includes oxidizers, organic peroxides, or explosives. A reactive chemical is one that: in the pure state, will vigorously polymerize, decompose, condense, or will become self-reactive under conditions of shocks, pressure, or temperature Violently reacts with exposure to water or air. Handle reactive chemicals with all proper safety precautions including designating a separate storage area, monitoring periodically for degradation, and using appropriate personal protection.


Compressed Gas Cylinders: Compressed Gas Cylinders Ensure compressed gas cylinders are: Properly secured with chains or straps. Cylinder caps in place during transport or not in use Properly labeled Empty cylinders are marked “EMPTY.” Check hoses, tubing, and regulators daily Please refer to UAF CHP if you use compressed gas cylinders (a lot of information!)


Lasers: Lasers If you work with lasers in your lab, see your supervisor for specific operating procedures. Laser Safety training is available through our office


Electrical Safety: Electrical Safety Electrical cords should be in good condition. All electrical equipment must be grounded using 3-pronged plugs. Do not overload circuits.

Health Hazards : Health Hazards Health Hazards The symbols shown below are often used to denote health hazards.


Health Hazard Symbols: Health Hazard Symbols General health hazard


Health Hazard Symbols: Health Hazard Symbols Poisonous


Health Hazard Symbols : Health Hazard Symbols Corrosives (cause tissue damage and burns on contact with skin or eyes)


Corrosive Chemicals: Corrosive Chemicals Capable of rapidly eroding building materials or metals Can burn, irritate or destructively attack organic tissues such as skin, eyes, lungs and stomach. Examples of commonly used chemicals that have corrosive properties are: acetic anhydride, bromine, chlorine, fluorine, glacial acetic acid, hydrochloric acid, hydrofluoric acid, nitric acid, potassium hydroxide, sodium hydroxide, sulfuric acid Safe handling procedures vary with each operation and the type/concentration of the corrosive chemical.


Acids and Bases: Acids and Bases When using acids and bases: Never pour water into acid. Slowly add the acid to the water and stir. Open bottles or carboys slowly and carefully, wearing protective equipment to guard hands, face, and body. Safety showers/eyewashes should be within 100 feet of the work area for quick drenching or flushing of the eyes and body.


Acids and Bases: Acids and Bases Concentrated acids and bases must be used in a fume hood. Never mix acid wastes with other materials such as solvents, metal-contaminated solutions, etc. Noncontaminated acid wastes can be easily disposed by neutralization (follow lab-specific SOPs). Flush empty disposable containers thoroughly with water before throwing them away. Each laboratory should have access to a spill kit that includes acid and base neutralizer Never use combustible organic materials (sawdust, excelsior, wood scraps and shavings, paper, rags, or burlap bags) to absorb or cleanup spillage.


Health Hazard Symbols: Health Hazard Symbols Radioactive


Radioactive Materials: Radioactive Materials Radioactive materials require special handling If you are required to use them, follow lab SOPs and/or obtain additional training through EHS&RM You must gain authorization from the UAF Radiation Safety Officer (RSO) to work with radioactive materials and apply to be come an authorized user or supervised user Contact your PI/CHO for more information


Health Hazard Symbols : Health Hazard Symbols Biological materials For more information contact the UAF Biosafety Officer x 5487


Acute Health Hazards : Acute Health Hazards Acute Health Hazards: effects occur immediately or soon after you come in contact with them. Examples: If you spill a strong acid on your hand, the acid will begin to burn immediately. You are working with a paint solvent in a closed area, and the vapors make you feel dizzy.


Chronic Health Hazards : Chronic Health Hazards Chronic Health Hazards: effects take years or decades to occur after many exposures. Example: Asbestos-related lung disease may take 20-40 years to appear after overexposure


Routes of Exposure : Routes of Exposure Chemicals can enter the body in four ways: 1. Inhalation 2. Skin absorption/contact 3. Ingestion 4. Injection


Routes of Exposure: Routes of Exposure Inhalation The most common exposure route May include breathing in dust, fumes, oil mist, gasses, or solvent vapors. Do not “sniff” to test chemicals!


Routes of Exposure: Routes of Exposure Skin absorption hazard Chemical is absorbed through the skin and enters the bloodstream. “Skin” on the MSDS means skin absorption hazard Skin contact hazard Chemical is capable of causing skin irritation or damage on contact. Corrosive chemicals can cause burns and tissue destruction.


Routes of Exposure: Routes of Exposure Skin absorption/Contact Wash promptly if a chemical has contacted your skin. Flush for at least 15 minutes prior to seeking medical attention. Avoid the use of solvents for washing skin. Solvents remove the natural protective oils from skin and can cause irritation and inflammation. In some cases, washing with solvent may facilitate absorption of toxic chemicals. This is why wearing protective clothing is important when working with chemicals.


Routes of Exposure: Routes of Exposure Ingestion Usually occurs by accident when eating or drinking around hazardous chemicals. Do not bring food (including gum and candy), beverages, tobacco, or cosmetic products into chemical storage or use areas. Wash your hands and face with soap and water after working with chemicals. Do not use mouth suction to pipette anything. Pipetting aids must be used at all times.


Routes of Exposure: Routes of Exposure Injection Can occur though sharps injuries. For instance, if you break a piece of glassware containing a hazardous chemical, the chemical can enter your bloodstream through the cut.

Controlling Physical and Health Hazards: Controlling Physical and Health Hazards There are three major ways to protect yourself: 1) Administrative Controls 2) Engineering Controls 3) Personal Protective Equipment (PPE)


Administrative Controls: Administrative Controls Product substitution (most desirable) Substitute highly toxic materials where possible (i.e. a higher LD 50) Less flammable/volatile (higher flash point and boiling point) Less corrosive (closer to a pH of 7) Limiting time around hazard Taking breaks, etc Training and communication This training, bulletin boards, safety meetings, MSDSs


Administrative Controls (Cont): Administrative Controls (Cont) Safe work practices No smoking, food or beverage in the labs. Do not use fume hoods for storage. Review MSDS first Avoid working alone


Administrative Controls (Cont): Administrative Controls (Cont) Safe work practices Maintain a clean, uncluttered work area. Know the location of the nearest two emergency exits and safety equipment (i.e, shower, eye wash stations.) Do NOT block access to emergency equipment, showers, eyewashes, fire extinguishers, exits and circuit breakers


Administrative Controls: Administrative Controls Exposure Monitoring (air sampling, etc) Performed when there is reason to believe that exposures may be in excess OSHA levels. If an employee would like to have an exposure assessment conducted, the CHO should be contacted (monitoring will be conducted by EHS&RM).


Administrative Controls: Administrative Controls Occupational Exams: you may be eligible for an occupational exam if: You develop signs or symptoms associated with exposure to hazardous chemicals in the laboratory. Warranted by exposure monitoring. Possible over-exposure during an accidental release.


Administrative Controls: Administrative Controls Proper chemical storage Segregate incompatible materials. Store corrosives & flammables below eye level. Store flammable materials in a flammable storage cabinet Store corrosives in a corrosive cabinet. Dispose of unused/outdated materials properly. Confine heavy objects to lower shelves. Store poisons/toxics in a secure location. Label the contents of all containers!


Administrative Controls: Administrative Controls Proper chemical storage Place chemicals in their proper storage areas at the end of each workday. Do NOT store chemicals on desks, laboratory bench tops, floors, fume hoods or in aisles. Each laboratory must have a puncture resistant (e.g., cardboard) container specifically designated for glassware disposal. Don’t put food/drinks in a refrigerator designated for chemical storage


Administrative Controls : Administrative Controls Proper waste disposal Do not drain liquid waste down the sink. Label all containers with approved labels. Do not allow waste to accumulate


Administrative Controls : Administrative Controls Proper waste disposal Empty containers: Water soluble solvents: triple rinse, deface the label, relabel as "Empty" and dispose with normal trash. Non-water soluble solvents: triple rinse using a solvent capable of removing the chemical. ALL rinsate must be collected in a hazardous waste disposal container. Deface the label, relabel as "Empty" and dispose with normal trash. Special procedures for P-Listed waste! Do not dispose of container Call UAF Hazardous Materials Section @ ext. 5487 for hazardous materials disposal.


Administrative Controls: Administrative Controls Spill Clean-up Procedures Attend to anyone who may have been contaminated. Notify occupants in the immediate area about the spill. Evacuate all nonessential personnel from the spill area. If the spilled material is flammable, turn off all ignition and heat sources; this includes magnetic stirrers.


Administrative Controls: Administrative Controls Spill Clean-up Procedures Avoid breathing vapors of the spilled material. Ensure that the fume hood(s) is on. Open windows where possible to increase exhaust ventilation. Secure cleanup supplies. Ensure protective apparel is resistant to the spill material. Confine or contain the spill to a small area. Use appropriate kit to neutralize and absorb inorganic acids and bases. Your Hazardous Materials Management Information binder gives procedures of who to call regarding a spill (pages 16-17 in Section 1 (Hazardous Waste Management Overview).


Engineering Controls: Engineering Controls The most common for labs are fume hoods and snorkel hoods Fume hoods are checked annually for adequate airflow. Verify: You have a sticker annotating this evaluation It is less than 1 year old. The sash is used at or BELOW the level of the sticker Call 474-5413 to schedule an evaluation if needed.


Fume Hood Failure: Fume Hood Failure In the event of a fume hood failure or low-flow alarm Discontinue fume hood operations Place lids on open containers, lower the hood sash and secure reactions that may be generating hazardous emissions. Contact Facilities Services Dispatch (474-7000). If the danger level is imminent, leave the lab immediately. If conditions warrant, i.e. concentrations are not higher than the LEL, activate the fire alarm via the pull down stations that are located near building exits. When arriving in a safe area, call 911.


Safe Practices for Fume Hoods: Safe Practices for Fume Hoods Conduct all operations that may generate air contaminants inside a hood Keep materials at least 6 in inside hood Do not block the opening of the back of the fume hood If large instruments are inside, place on blocks so air current can move underneath. Do not store chemicals in a hood.


Personal Protective Equipment: Personal Protective Equipment Protective Clothing A full-body-length rubber, plastic, or neoprene apron appropriate for the material being handled should be worn if there is risk of splash or spill. Lab coats, tyvek garments, and sleeve covers are other examples


Personal Protective Equipment: Personal Protective Equipment Eye Protection Safety glasses, chemical-resistant goggles, or face shields shall be worn at all times in labs where chemicals are being used. This includes visitors.
