JCPS CHEMICAL HYGIENE TRAINING

29 CFR 1910.1450OCCUPATIONAL EXPOSURE TO HAZARDOUS CHEMICALS IN

LABORATORIES

PURPOSE:

1) Protect lab personnel and JCPS students

2) Compliance with OSHA 1910.1450A 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.


RESPONSIBLITIES:Chemical Hygiene Officer (CHO)Laboratory Science Chairperson(s)Laboratory Science Teachers


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

CHEMICAL HYGIENE PLANRESPONSIBILITIES

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

(CHP) RESPONSIBILITIES

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 LabNO Horseplay NO Open-toed shoesNO Working aloneNO Unauthorized PersonnelConfine long hair and loose clothingReport ANY unsafe conditions and/or laboratory incidents

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 HYGIENE FUME HOOD FIRES

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 ADMINISTRATIVE CONTROLS

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

CHEMICAL HYGIENE – PPE

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

CHEMICAL HYGIENE CHEMICAL SAFETY

SAFETY DATA SHEETS (SDS)

LABELING:1) Name of product

2) Signal Word (DANGER, WARNING)

3) Pictogram of health hazard/physical hazard

4) Hazard Statement (fatal if swallowed, toxic if swallowed, harmful if swallowed)

5) Pre-Cautionary Statement (wear eye protection, etc.)

6) Manufacturer/Supplier Contact Info (name, address and telephone number)


CHEMICAL SAFETY - LABELING

ROUTES OF EXPOSURE:

1)Inhalation by breathing dusts, fumes, mists or vapors.

2)Ingestion by eating or drinking with contaminated hands or in a contaminated laboratory.

3)Absorption through the skin or eye by contact with liquid, dusts, fumes, mists or vapors.


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


Physical Hazards:

OxidizersFlammablesCombustiblesOrganic peroxidesPyrophoricWater reactive


FIRE HAZARD DIAMOND

DISPOSAL METHODSDispose of all chemicals properlyThe 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.


DISPOSAL METHODSNever pour chemicals down the drain unless authorized

Never mix chemicals with regular trash

Never Combine Waste!Request a waste pick-up when needed


STORAGENever 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


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, orb) safety cans, orc) 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

CHEMICAL HYGIENELABORATORY INSPECTION

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.

CHEMICAL HYGIENE GENERAL EMERGENCIES

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.
