Workplace Labels

• Workplace labels are to be used for any products

that are decanted from one container to another container.

• You can obtain blank workplace labels from your

Supervisor and fill them in or print them directly from the MSDS on-line database.

• It is also acceptable to label the bottle or container

using a permanent marker provided that all the required information is included.

• Workplace labels can also be used if the supplier

label has been accidentally removed or defaced.

MSDS Contents

 Product Information  Hazardous Ingredients  Preparation Information  Physical Data  Fire & Explosion Data  Reactivity Data  Toxicological Properties  Preventative Measures  First Aid Measures

There are 9 main sections of information in an MSDS required under Canadian regulations.

York Region District School Board WHMIS Refresher – School Staff Health & Safety Human Resource Services

Product Information

 Product Identifier  Manufacturer’s/Supplier’s Name and

Address

 Emergency Telephone Number  Product Use

York Region District School Board WHMIS Refresher – School Staff Health & Safety Human Resource Services

Why is this information important?

 This information can be used to verify that you have

the right MSDS for the material you are using.

 The material name on the MSDS must match the

name on the container’s WHMIS label.

York Region District School Board WHMIS Refresher – School Staff Health & Safety Human Resource Services

Hazardous Ingredients

 Chemical Identity  CAS Number  LD50 Species and

Route

 LC50 Species and

Route

 Concentration  PIN Number

York Region District School Board WHMIS Refresher – School Staff Health & Safety Human Resource Services

Why is this information important?

 This section tells you what is in the product and in

what proportion.

 Provides information on the toxicity levels.  If the CAS, (Chemical Abstract Service) number is

available, it can save confusion as to what each chemical is during an emergency.

York Region District School Board WHMIS Refresher – School Staff Health & Safety Human Resource Services

Preparation Information

 Prepared by (Group, Department, etc.)  Phone Number  Date of Preparation

York Region District School Board WHMIS Refresher – School Staff Health & Safety Human Resource Services

Why is this information important?

 This section tells you who to contact for more

information.

 The MSDS is only good for three (3) years from the

date of preparation. Therefore, the revision date plus three years is equivalent to the expiry date.

York Region District School Board WHMIS Refresher – School Staff Health & Safety Human Resource Services

Physical Data

 Odour Threshold  Vapour Pressure  Coefficient of Water/Oil

Distribution

 Boiling Point (oC) and

Freezing Point (oC)

 Evaporation Rate (Butyl

Acetate=1)

 Physical State  Odour & Appearance  Specific Gravity

(Water=1)

 Vapour Density (Air=1)  pH  Percent Volatile (by

volume)

York Region District School Board WHMIS Refresher – School Staff Health & Safety Human Resource Services

Why is this information important?

 This section tells you whether or not you are using

the right product (appearance and odour). Much of the information provided in this section is of a technical nature and is used by engineers,

• ccupational hygienists, fire fighters and others who

may be directly involved in the planning of controls.

York Region District School Board WHMIS Refresher – School Staff Health & Safety Human Resource Services

Fire & Explosion Hazard

 Conditions of Flammability  Means of Extinction  Sensitivity to Mechanical Impact  Sensitivity to Static Discharge  Flashpoint (oC) and Method  Upper and Lower Flammable Limits (%)  Autoignition Temperature (oC)  Hazardous Combustion Products

York Region District School Board WHMIS Refresher – School Staff Health & Safety Human Resource Services

Why is this information important?

 This section tells you if the product you are using

presents a fire hazard.

 It also outlines the appropriate extinguishing agents

to use in case of a fire e.g., CO2, water

York Region District School Board WHMIS Refresher – School Staff Health & Safety Human Resource Services

Reactivity Data

 Stability  Incompatible Materials  Conditions of Reactivity  Hazardous Decomposition Products

York Region District School Board WHMIS Refresher – School Staff Health & Safety Human Resource Services

Why is this information important?

 This section tells you how to use the product safely.

For example, if the material reacts with metal, you should store it on a non-metal shelf. Some materials may react with other common materials to produce toxic by-products. For example, the mixing of ammonia and bleach produces highly toxic chlorine gas.

York Region District School Board WHMIS Refresher – School Staff Health & Safety Human Resource Services

Toxicological Properties

 Irritancy to Product  Effects of Acute

Exposure

 Evidence of

Carcinogenicity, Reproductive Toxicity, Teratogenicity or Mutagenicity

 Routes of Entry  Exposure Limits  Synergistic Products  Sensitivity to Product  Effects of Chronic

Exposure

York Region District School Board WHMIS Refresher – School Staff Health & Safety Human Resource Services

Why is this information important?

 This sections tells you how the material may enter

your body and the adverse effects (if any) of

• verexposure to the product.

York Region District School Board WHMIS Refresher – School Staff Health & Safety Human Resource Services

Preventative Measures

 At the Source- Engineering Controls  Along the pathway- Preventing dispersion  Personal Protective Equipment  Leak and Spill Procedure  Waste Disposal  Handling Procedures and Equipment  Storage Requirements

York Region District School Board WHMIS Refresher – School Staff Health & Safety Human Resource Services

Why is this information important?

equipment is required, how to deal with a spill, what preventive measures such as fans, opening windows should be used and how to dispose of the material.

York Region District School Board WHMIS Refresher – School Staff Health & Safety Human Resource Services

First Aid Measures

 Inhalation  Eye Contact  Ingestion  Skin Contact

York Region District School Board WHMIS Refresher – School Staff Health & Safety Human Resource Services

Why is this information important?

 This section tells you what steps you should take if

someone is accidentally exposed to the product.

York Region District School Board WHMIS Refresher – School Staff Health & Safety Human Resource Services

Additional Information

 MSDSs must be readily available  3 year expiry date  New information becomes available

York Region District School Board WHMIS Refresher – School Staff Health & Safety Human Resource Services

Emergency Preparedness

 It is important to be prepared for emergencies

involving chemicals.

 This includes chemical spills, fire and/or first aid

emergencies.

WHMIS Review

 Read the MSDS before working with a product to ensure that you

know how to safely use, handle and store the product.

 Never mix chemicals, only use products for their intended use.  Know when personal protective equipment is required and where

it is located at your school. The MSDS will tell you what personal protective equipment is required. Never change the type of personal protective equipment stated such as “rubber gloves for vinyl”.

 Know where spill kits and first aid kits are located at your school.

Teachers are responsible for cleaning up small spills of chemicals used in art, technology or science. For large chemical spills, call

• 911. Also, contact Health and Safety at 2343 to make

arrangements for proper disposal of the liquid hazardous waste.

York Region District School Board WHMIS Refresher – School Staff Health & Safety Human Resource Services

WHMIS Review cont’d



Consumer products are included on the chemical inventory found at the front of each MSDS binder. We obtain MSDS for these products even though they are not required. They will appear as “INFO” under the Product Control section on the Chemical Inventory.



Only Board-approved consumer products are permitted in our schools unless they are personal care products such as hand cleaner and only being used by the individual who brought it in.



It is not a caretaker’s responsibility to store or dispose of hazardous liquid wastes generated by art, technology or science classes. Materials may be stored for safety reasons in the bunker or exterior storage area until picked up. Teachers are responsible for transfer of the waste and must have the appropriate spill containment materials.



A MOL inspector may visit your school and assess your knowledge and understanding of WHMIS and/or access to the MSDS binders.
