 Ensure that chemical hygiene training has been completed (annually)
 Immediately report all accidents, near misses and unsafe conditions

CHEMICAL HYGIENE PRACTICES
 Minimize quantities of chemicals used and stored in the laboratory. Minimize concentrations in solutions/mixtures
 Avoid an underestimation of risk: It should always be assumed that the toxicity of a mixture would be more toxic than its most toxic component
 All substances of unknown toxicity should be considered toxic
 Unauthorized experiments shall not be performed
 Do not allow students to smell/taste chemicals
 Do not use chipped or cracked glassware

CHEMICAL HYGIENE PRACTICES
 NO Eating or Drinking in the Lab
 NO Horseplay
 NO Open-toed shoes
 NO Working alone
 NO Unauthorized Personnel
 Confine long hair and loose clothing
 Report ANY unsafe conditions and/or laboratory incidents

HEIRARCHY OF CONTROLS

ENGINEERING CONTROLS

EMERGENCY SAFETY SHOWERS
 Flush contaminated area with water
 Remove contaminated clothing
 Rinse with water for 15 minutes
 Seek medical attention if needed

FUME HOODS
 Do not use the fume hood as a storage area or block the hood exhaust flow
 Never lean into fume hood while hazardous chemicals are being used
 Keep work at least six (6) inches inside the hood face
 Make sure fume hood are operating and fully functioning (75-100 fpm)

 Chemical substitution
 Proper storage and segregation of hazardous materials
 Proper housekeeping practice
 Prudent inventory and purchase order management
 Appropriate training and Right to Know information
(such as SDS)

CHEMICAL HYGIENE
HOUSEKEEPING
 Keep all aisles and passageways free of clutter and debris
 Keep floors dry and free from slip hazards
 Wash hands thoroughly before leaving the laboratory
 Clean up broken glass and spills immediately
 Dispose of chemicals, broken glass, and other waste in approved containers

PERSONAL PROTECTIVE EQUIPMENT
 Eye Protection
 Lab Aprons
 Gloves
 Close-Toe Shoes

CHEMICAL HYGIENE
CHEMICAL SAFETY
SAFETY DATA SHEETS (SDS)
 Describe the physical characteristics of hazardous chemicals
 Provide information about the chemical’s physical and chemical hazards
 List the means for controlling those hazards
 Provides information about first aid, waste disposal, emergency procedures and exposure limits

SAFETY DATA SHEETS (SDS)

STORAGE
• Store chemicals on sturdy shelves, away from edge, on shelves w/ lips
• Storage must be in: a) closed metal containers inside a storage cabinet, or b) safety cans, or c) an inside storage room

 Conducted on a Monthly basis
 Inspect fume hoods, eye wash and safety shower for any defects or deficiencies
 Inspect chemicals for proper labeling, storage and containment
 Ensure that student are wearing appropriate PPE
 Ensure that SDS/MSDS and Chemical Hygiene Plan are available

1) Rescue anyone immediately affected by the emergency. Only perform rescue if it does not put yourself at risk.
2) Notify emergency personnel by calling 911 and the District
Operations Center (DOC) at 3121.
3) Warn others in the area about the emergency and stay clear.
4) Turn off any ignition sources such as burners or other open flames.
5) Follow the directions of the Emergency responders. Do not re-enter the area until the area is deemed safe to return.

1) If the skin becomes contaminated with hazardous chemicals, wash the affected area with copious amounts of water. Use the emergency shower for at least fifteen (15) minutes.
2) Use eye wash station if chemicals are splashed into the eye.
Flush for at least fifteen (15 minutes).
3) Remove contaminated clothing immediately and discard.
4) Consult the SDS/MSDS.
5) Seek medical attention and report spill to emergency responders to include: type of emergency, name of chemical spilled, area of spill, corrective action and name(s) of exposed.
