JCPS CHEMICAL HYGIENE TRAINING

29 CFR 1910.1450 OCCUPATIONAL EXPOSURE TO HAZARDOUS CHEMICALS IN LABORATORIES

CHEMICAL HYGIENE PLAN (CHP) PURPOSE: Protect lab personnel and JCPS students Compliance with OSHA 1910.1450 A Chemical Hygiene Plan (CHP) is a legal document that is required by OSHA when working with hazardous chemicals in a laboratory.

CHEMICAL HYGIENE PLAN (CHP) SCOPE & APPLICATION: Applies to all JCPS laboratories that use, store or handle potentially hazardous chemicals, and all personnel who work in these facilities.

CHEMICAL HYGIENE PLAN (CHP) RESPONSIBLITIES: Chemical Hygiene Officer (CHO) Laboratory Science Chairperson(s) Laboratory Science Teachers

CHEMICAL HYGIENE PLAN RESPONSIBILITIES Chemical Hygiene Officer JCPS Environmental Coordinator Identifies personnel affected by compliance requirements Updates & maintains the Chemical Hygiene Plan (CHP) Monitors procurement, use, storage and disposal of chemicals Conducts periodic inspections of labs and chemical storage Maintains inspection, training and inventory records Assists science chairpersons and science laboratory teachers Ensures that monthly science lab inspection forms are completed

CHEMICAL HYGIENE PLAN RESPONSIBILITIES Laboratory Science Chairperson(s): Assumes responsibility for personnel engaged in lab work Provides chemical hygiene officer with support for CHP Meets with science lab staff to discuss safety/health hazards Ensures that the department remains in compliance with all applicable federal, state and local codes/regulation Ensures the safety and health of all personnel and JCPS students Ensures that lab science staff are trained on the CHP (annually) Ensures that lab science staff completes monthly lab inspections

(CHP) RESPONSIBILITIES Laboratory Science Teachers: Review and follow the requirements of the CHP Follow all lab safety rules, regulation and procedures Identify hazardous conditions or operations Maintain lab safety equipment to ensure it is in proper working order Develop and practice good personal chemical hygiene habits Ensure that appropriate PPE (aprons, glove, glasses, etc.) are made available, in good working order, and used properly Conduct monthly laboratory inspections and identify any hazards 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

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)

CHEMICAL HYGIENE CHEMICAL SAFETY LABELING: Name of product Signal Word (DANGER, WARNING) Pictogram of health hazard/physical hazard Hazard Statement (fatal if swallowed, toxic if swallowed, harmful if swallowed) Pre-Cautionary Statement (wear eye protection, etc.) Manufacturer/Supplier Contact Info (name, address and telephone number)

CHEMICAL SAFETY - LABELING

CHEMICAL HYGIENE CHEMICAL SAFETY ROUTES OF EXPOSURE: Inhalation by breathing dusts, fumes, mists or vapors. Ingestion by eating or drinking with contaminated hands or in a contaminated laboratory. Absorption through the skin or eye by contact with liquid, dusts, fumes, mists or vapors.

CHEMICAL HYGIENE CHEMICAL SAFETY Health Hazards: Irritants (respiratory/skin/eyes) Hepatotoxins (liver toxins) Nephrotoxins (kidney toxins) Corrosives Neurotoxins (act on nervous system) Possible Carcinogens (teratogens/mutagens)

CHEMICAL HYGIENE CHEMICAL SAFETY Physical Hazards: Oxidizers Flammables Combustibles Organic peroxides Pyrophoric Water reactive

FIRE HAZARD DIAMOND

CHEMICAL HYGIENE CHEMICAL SAFETY DISPOSAL METHODS Dispose of all chemicals properly The chemical SDS/MSDS can assist with disposal methods Recommend consulting your current Flinn Scientific Catalog/Reference Manual for general guidelines and specific procedures governing the disposal of laboratory wastes.

CHEMICAL HYGIENE CHEMICAL SAFETY DISPOSAL METHODS Never pour chemicals down the drain unless authorized Never mix chemicals with regular trash Never Combine Waste! Request a waste pick-up when needed

CHEMICAL HYGIENE CHEMICAL SAFETY STORAGE Never store chemicals over, under or near a sink Do not store or allow unlabeled chemicals anywhere in school Keep all chemicals in a locked storage area when not in use Store incompatible chemicals in separate storage areas

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

CHEMICAL HYGIENE LABORATORY INSPECTION 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

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

CHEMICAL SPILLS 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. Use eye wash station if chemicals are splashed into the eye. Flush for at least fifteen (15 minutes). Remove contaminated clothing immediately and discard. Consult the SDS/MSDS. 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.
