Permissible Exposure Limit (PEL) “The maximum allowable concentration of an airborne contaminant to which a worker can be exposed over an 8-hr workday and 40-hr workweek.” http://www.osha.gov
PEL (ppm) Ammonia 50 Benzene 1 Carbon tetrachloride 10 Hexane 500 Methanol 200 Toluene 200
Chemical-Specific Standards • Benzene • Benzidine • Methylene Chloride • Formaldehyde • Acrylonitrile • Etc.
Chemical Management • Inventory Control • Chemical Storage • Other Issues
Inventory Control • Designate responsibilities • Provide training • Require prior approval • Require monthly inventory • Purchase limited amount • Choose least hazardous chemicals • Inspect regularly & conduct periodic audits • Establish chemical tracking system
Chemical Storage: General Rules • Proper ventilation • Shelving system • Eye level • Secured • No floor storage • Anti-roll lips
Chemical Storage: General Rules • Master controls • Emergency communication • Emergency equipment: • Fire extinguisher • Spill kit • Eye washer/shower
Storage Principles • Supervision & security • DO NOT store alphabetically • Separate/segregate by compatibility • Spill containment
Segregation • Review MSDS & safety information • Assign classes • Prevention of fire, explosion, toxic exposure • Manageable number of classes • Initial classes: toxic, flammable, reactive, corrosive, low hazards
Example: Storage Segregation Scheme Class Types 1 Flam/Combus, toxic, low toxic Compatible with water 2 Same as 1, but non-compatible with water 3 Oxidizer, non-flam/non-combus, toxic, low toxic Compatible with water 4 Same as 3, but non-compatible with water 5 Air sensitive 6 Require refrigeration 7 Compressed gas cylinder 4 groups: oxidizer, reducer, corrosive, toxic 2 subgroups: empty, full 8 Unstable (explosives, short shelf life, etc)
Storage in Laboratory • Small amounts • Sealed and secured • Limited access • Label and warning signs • Segregation
Storage in Laboratory • Flammable & combustible liquids • Minimize amounts • Safety cans • Flammable cabinet
Two exits Fire sprinkler & fire alarm PPE & emergency equipment Ventilation Diked floor Emergency shower/eye washer Explosion proof electrical lights, ventilation motors, etc. Stockroom
Spill Containment • Drip pan • Lips on shelves • Drum containment • Dikes on floor
YOUR SAFETY FIRST! • Attend to injured/ • contaminated victim • Turn on fume hoods • Open windows • De-energize electrical devices SMALL SPILLS • Select proper PPE • Neutralize acids and bases • Absorb liquids • Collect and contain residue • Decontaminate area & equipment • Document incident
Other Issues • Labels • Accessibility control • Housekeeping & floor storage • Compressed gas cylinders • Emergency showers/eye washers
Example: Label Toluene (Toluol) WARNING! Flammable Vapor Harmful 3 2 0 Keep away from heat and open flame. Keep container closed. Use only with adequate ventilation. Avoid prolonged breathing of vapor. Avoid prolonged or repeated contact with skin. Do not dispose of in building drains. Flash Point 4°C (40 °F)
NFPA 704 • Colors • Blue: Health hazards • Red: Flammability hazard • Yellow: Reactivity hazard • White: Special information • Numbers • 0 to 4 • The higher the number, the greater the hazard NFPA: National Fire Protection Association
Accessibility Control • Authorized personnel only • Entry secured • Contact information posted
Basic Safety for Gas Cylinders • Know the hazards • Use proper footwear • Use cylinder cart to transport • Do not drop, roll • Secure when storing and close valves when not in use • Mark empty cylinder
