Information Elements Required on a WHMIS 2015 Safety Data Sheet (SDS)

WHMIS 2015 sets out requirements for safety data sheets (SDS) in Part 4 of the Hazardous Products Regulations (HPR).  Schedule 1, of the HPR, sets out the 16-heading SDS format and the content required under each of the 16 headings.  That content is summarized here for ease of reference.

Disclaimer
 
Information contained in this section is of a general nature only and is not intended to constitute advice for any specific fact situation. For particular questions, users should contact their legal advisor and/or the occupational health and safety authority having jurisdiction for their workplace.

SDSs must be in both English and French. This information may appear either on a single bilingual SDS or on two separate unilingual documents that constitute one bilingual SDS.

SDSs must be updated to include significant new information - information which changes the classification of the hazardous product or ways to protect against the hazards presented by the product - within 90 days of becoming available.  In the interim 90-day period, upon sale of the hazardous product, that information must be communicated, in writing, to any purchaser of the product.

Requirements
(Specific Information Element)
1. Identification Requirements consist of:
(a) product identifier;
(b) other means of identification;
(c) recommended use and restrictions on use;
(d) initial supplier identifier; and
(e) emergency telephone number and any restrictions on the use of that number, if applicable.
2. Hazard identification Requirements consists of:
(a) classification of the hazardous product,  (e.g. Carcinogenicity, Category 1);
(b) the symbol, signal word, hazard statement and precautionary statement, for each of the applicable classes . If the required information element is a symbol, either the name of the symbol or the symbol itself may be used; and
(c) other hazards known to the supplier with respect to the hazardous product.
3. Composition/ Information on ingredients Requirements consist of:
(1) If the hazardous product is a material or substance,
(a) its chemical name;
(b) its common name and synonyms;
(c) its CAS registry number and any unique identifiers; and
(d) the chemical name of the impurities, stabilizing solvents and stabilizing additives that are known to the supplier, that individually are classified in any category or subcategory of a health hazard class and that contribute to the classification of the material or substance.
Requirements consist of:
(2) If the hazardous product is a mixture, provide the
(a) chemical name;
(b) common name and synonyms;
(c) CAS registry number and any unique identifiers; and
(d) concentration of each material or substance in the mixture that, individually, is classified in a health hazard class and is present above the concentration limit for that class or, if not above the concentration limit, is present in the mixture at a concentration that results in the mixture being classified in any health hazard class.
4. First-aid measures Requirements consists of:
(a) a description of necessary first-aid measures, subdivided according to the different routes of exposure (inhalation, ingestion, skin and eye contact);
(b) the most important symptoms and effects, whether acute or delayed; and
(c) an indication of immediate medical attention and special treatment needed, if necessary.
5. Fire-fighting measures Requirements consists of:
(a) suitable and unsuitable extinguishing media;
(b) specific hazards arising from the hazardous product, such as the nature of any hazardous combustion products; and
(c) special protective equipment and precautions for fire-fighters.
6. Accidental release measures Requirements consist of:
(a) personal precautions, protective equipment and emergency procedures; and
(b) methods and materials for containment and cleaning up.
7. Handling and storage Requirements consist of:
(a) precautions for safe handling; and
(b) conditions for safe storage, including any incompatibilities.
8. Exposure  Controls/ Personal
protection
Requirements consist of:
(a) control parameters, including occupational exposure limit values or biological limit values and the source of those values;
(b) appropriate engineering controls; and
(c) individual protection measures, such as personal protective equipment.
9. Physical and chemical properties Requirements consists of:
(a) appearance, such as physical state and colour;
(b) odour;
(c) odour threshold;
(d) pH;
(e) melting point and freezing point;
(f) initial boiling point and boiling range;
(g) flash point;
(h) evaporation rate;
(i) flammability, in the case of solids and gases;
(j) upper and lower flammability or explosive limits;
(k) vapour pressure;
(l) vapour density;
(m) relative density;
(n) solubility;
(o) partition coefficient -- n-octanol/water;
(p) auto-ignition temperature;
(q) decomposition temperature; and
(r) viscosity.
10. Stability and reactivity Requirements consists of:
(a) reactivity;
(b) chemical stability;
(c) possibility of hazardous reactions;
(d) conditions to avoid, including static discharge, shock or vibration;
(e) incompatible materials; and
(f) hazardous decomposition products.
11. Toxicological information Requirements consists of:
Concise but complete description of the various toxic health effects and the data used to identify those effects, including
(a) information on the likely routes of exposure (inhalation, ingestion, skin and eye contact);
(b) symptoms related to the physical, chemical and toxicological characteristics;
(c) delayed and immediate effects, and chronic effects from short-term and long-term exposure; and
(d) numerical measures of toxicity, including Acute Toxicity Estimates (ATEs).
12. Ecological information While the heading of this section is required to preserve the SDS 16-heading format, content within this section is optional.
Content consists of:
(a) ecotoxicity (aquatic and terrestrial, if available);
(b) persistence and degradability;
(c) bioaccumulative potential;
(d) mobility in soil; and
(e) other adverse effects.

Content consists of:
Information on safe handling for disposal and methods of disposal, including any contaminated packaging.
14. Transport information While the heading of this section is required to preserve the SDS 16-heading format, content within this section is optional.
Content consists of:
(a) UN number;
(b) to (d) United Nations proper shipping name,  transport hazard class, and packing group, as provided for in the UN Model Regulations;
(e) environmental hazards according to the International Maritime Dangerous Goods Code and the UN Model Regulations;
