Chemical Hygiene Plan: An Overview

What is Chemical Hygiene Plan?

Purpose of Chemical Hygiene Plan?




A Chemical Hygiene Plan is • a written program • developed and implemented by the employer • Details of procedures, equipment, personal

protective equipment and work practices • To ensure protection of workers from the

health hazards presented by hazardous chemicals used in that particular workplace


Purpose of Chemical Hygiene Plan?


1. Uniform Manner in which chemicals are to be

procured, stored and disposed

2. Plan for management of Emergencies

involving chemicals

3. Ensures compliance with guidelines of

regulatory agencies

What is Chemical Hygiene Plan:

1. Policy Statement

2. Scope, Definitions & Applications

3. Purpose

4. Responsibilities

5. Facilities

6. Hierarchy of Controls (Engineering)

7. Basic Rules & Procedures (PPE No Food…)



• Institutional (generic) and Area-wise (Specific)

• Responsibilities

• Hazard Identification

• Hazard Information

• Hazard Communication

• Training

• S.O.P


Chemical Hygiene Plan: Inventory

• Unit-wise • Master Inventory (CHO) • Update annually

• The inventory contains the following: • An alphabetized list of IUPAC names or

trade name • CAS number • Hazard Word/Statement/Hazard/Note • Quantity stored (Average)


Chemical Hygiene Plan: Information

Information about hazardous chemicals?

Two ways:

•from the product label

•from the product Safety Data Sheet


Chemical Hygiene Plan: Hazard Information


Chemical Hygiene Plan: Hazard Communication

• Signage

• Labels

• Secondary Container Labeling

• Secondary Labels

• S. O. P. (procedure specific; chemical specific)


Chemical Hygiene Plan: Training

•Awareness on Safety issues

•Communicate Responsibilities

•Familiarize Standard Operating Procedures (SOPs)

•Establish and Ensure Compliance to National/State Regulatory guidelines

•Should be as part of induction program •Before involving new tasks/new chemicals Before being assigned to a laboratory •Update periodically – refresher & update


Information – SDS; Hazcom ; Safety Program Emergency Procedures; Receiving & Stock Room Personnel (CRS)

Chemical Hygiene Plan: Activities

1. Procurement, Distribution & Storage 2. Monitoring for Airborne Concentration 3. Housekeeping, Maintenance & Inspections 4. Medical Program: Surveillance, work

related injuries, illness or toxic exposure 5. PPE 6. Records 7. Hazcom: Signage and Secondary Labels 8. Incident Management: Spills, Splashes etc 9. Information & Training 10. Waste Disposal

Chemical Hygiene Plan

Chemical Hygiene Plan: Procurement

• Protocol for introducing a new chemical: • Obtain a SDS prior to shipment • Provide SDS to EC and CHO • Ensure adequacy of engineering controls &

PPE • Order the smallest quantity of the chemical • Update their chemical inventory • CHO to update master inventory

Chemical Hygiene Plan: Environmental Monitoring

Monitoring Airborne concentrations of certain chemicals

• Regular monitoring not practical or justified • Except

• Initially to ensure within permissible limits • Quality control for Engineering Control • Mandatory (regulatory agency) • Compromise in safety devices/personnel

exposure • Redesigning facility


Chemical Hygiene Plan: Medical Care

Care for the Care Givers


• Surveillance

• Work-related exposure

• Work-related Injury

• Exposure Management

• Signs or symptoms of overexposure

• Suspicion of exceeding exposure limits

• Health Care offered as appropriate

• Periodic Monitoring

Chemical Hygiene Plan: Housekeeping

Maintenance Inspection Also for eye wash stations & showers

Chemical Hygiene Plan: Routes of Entry & Personal Protective Equipment

Chemical Hygiene Plan: Records

Disposal of • Waste • Unused • Expired • Surplus

• Destruction Certificate

• Regulated Chemicals


Chemical Hygiene Plan: Hazcom


Chemical Hygiene Plan: Incident Management


• Small or Large • Minor or Major

• Assess • Inform (Buddy) • Contain • Neutralize • Clean-up or Call for Help • Remove

(Absorbent/Drain) ;

• Always Record /Report

Chemical Hygiene Plan: Incident Management

Chemical Splash


Chemical Hygiene Plan: Waste Disposal Waste Identification and Management •SDS - determine hazard class •collection, handling & disposal of all hazardous wastes Hazardous waste can be accumulated at or near the point of generation. This is referred to as the a Satellite Accumulation Area (SAA).


Chemical Hygiene Plan: Right to Know


Chemical Hygiene Plan: Summary


• Policies • Procedures • Train (Communicate & Educate) • Implement • Monitor • Evaluate • Sustain • Raise the Bar Beyond Compliance


Whichever way you exit this hall

Our wish is that you go back and establish

a proper chemical hygiene plan Which will

always lead you to safety and

And now

“TOXIC” Jeopardy

What is….”Improper Chemical

Storage!!”

What is: “food storage in a

refrigerator with toxic chemicals”

What is: “Improperly labeled

container”

What is: „Funnel –in-throat” container

What is: “old chemicals, some open,

bad housekeeping”

What is: “improperly labeled waste

container on a sink”…

What is: “„Funnel –in-throat” container”

What is: “ improperly

labeled container”

What is: “ unlabeled containers”

What is: “ an unknown, waste-like

container”

What is: “inherently waste-like

container”

What is: “improperly labeled containers-

two labels / label over original ”

What is: “Improper disposal of a

hazardous waste”

What is: “Potpourri” You name it!!

All of the above

EHHHHH!!! The wrong way!!

Summation

• Though presented in a humorous manner, the above

slides are very serious from a health and safety point

of view

• There are some serious and potentially hazardous

conditions demonstrated

• One chemical among some shown above, if

mishandled can result in…

Peroxide Crystals formed from

Isopropyl Ether

http://home.cyberave.com/~rhr/bigiso.htm

Another bottle from the same college’s laboratory that

has peroxidized, with a light-impact detonation cap.

The resulting detonation left a crater in the ground approximately three foot wide by one foot deep !

This could easily have occurred in the lab if

bumped or heated

A laboratory chemical that has been

stored/handled improperly can be

hazardous to your health!

Three 5 gal. containers of peroxidized Tetrahydrofuran at @ 120 o F!!

Good Chemical Handling / Storage

• Check your inventories……

• Get rid of what you do not need

• Manage those containers with bad labels

• Manage waste collection containers with correct

labeling of contents, and keep caps closed when not

adding to them

• Make sure all chemicals have proper labels and are

within expiration dates / known shelf lives

Laboratory Documentation

• RPI, Registration (Posted)

• Safety Inspections

• Hazard Assessments

• Prior Approval

• Check in/Check out

• SAA Weekly Inspections

• Fume Hood Logs

• Autoclave Logs & QC Logs
