Safety Data Sheet
What specific structure must an SDS follow under WHMIS 2015, and how does this align with OSHA?
Under WHMIS 2015, SDSs must follow a standard 16-section format consistent with the GHS, including sections like Identification, Hazard identification, Composition, First-aid measures, Fire-fighting measures, Accidental release measures, Handling and storage, Exposure controls, Physical and chemical properties, Stability and reactivity, Toxicological information, and others. OSHA's Hazard Communication Standard (2012 revision) requires the same 16-section format, harmonized with GHS.
When must a Canadian employer prepare its own SDS versus using the supplier's SDS?
Under Canada Occupational Health and Safety Regulations, if an employer produces a hazardous product in the workplace (e.g., custom blend) or imports one without a compliant supplier SDS, they must prepare a workplace SDS complying with HPR requirements. For products produced and used exclusively in that workplace, an employer-authored SDS may be required instead of relying solely on supplier documents.
What are the retention and update requirements for SDSs under federal Canadian guidance and WorkSafeBC?
Federal guidance requires employers to review and update SDSs at least every three years. When a hazardous product is received, employers must obtain a supplier SDS without delay unless a current SDS (< 3 years old) is on file. If an SDS is three years or older, employers must, if practicable, obtain a current SDS from the supplier. WorkSafeBC echoes this, stating SDSs must be checked every three years to ensure current information.
A Safety Data Sheet (SDS) is a standardized technical document required under WHMIS 2015 in Canada and OSHA's Hazard Communication Standard in the US. It provides detailed information about a hazardous product, including its hazards, safe handling, storage, emergency response, and regulatory data, following a 16-section GHS format to ensure worker safety and compliance.
On a manufacturing shop floor, SDSs are essential for hazard identification, safe handling, PPE selection, storage segregation, and emergency response. Workers use them to identify hazard classes (e.g., flammable, corrosive) and risk phrases. SDSs guide mixing, dilution, and transfer procedures, and inform selection of respirators, gloves, and ventilation systems. Storage layouts for flammable or corrosive cabinets are based on SDS incompatibility data. Spill kits and fire response plans are designed using SDS first-aid and accidental release measures. SDSs also support exposure recognition, health surveillance, and training content. In digital systems like SafeDesk, SDSs are catalogued by product name and location, linked to inventory, made accessible via kiosks or tablets, and used to auto-populate risk assessments and training modules, ensuring regulatory compliance and audit readiness.
Outdated or missing SDSs: Employers maintain SDSs older than 3 years or lack SDSs for some hazardous products, leading to incorrect hazard classifications, PPE recommendations, or emergency procedures, increasing exposure risks.
SDSs not readily accessible to workers: SDSs are locked in offices or stored only electronically without floor access, preventing workers from consulting them before use or in emergencies, causing incorrect spill cleanup or PPE misuse.
SDS content not integrated into procedures or training: SDSs exist but are not incorporated into safe work procedures, WHMIS training, or emergency plans, resulting in generic training lacking product-specific knowledge like exact respirator type or reactivity hazards.
