A 2017 SDS, Missing Section Detail, and a Night-Shift Worker
A metal fabrication shop introduces a new parts-washing solvent. The supplier provides a 16-section SDS dated 2017. Sections 1, 2, 3, and 9 are complete, but Section 8 lists only 'use local exhaust' and gives no exposure limits; Section 4 says 'seek medical attention' without specific first aid measures. The product label is legible and includes the required pictograms. A worker who speaks little English will use the solvent on the night shift. The only WHMIS training on record is a 10-minute generic video shown at orientation 18 months ago; no site-specific training, SDS location, or hands-on instruction was provided. After 45 minutes near the wash tank, the worker reports dizziness and headache. The supervisor says the SDS is 'old but still valid' and that the video covers WHMIS.
1. What SDS deficiencies should the employer address, and is the 2017 date by itself a reason to reject the SDS?
Read the worked answer
The date alone is not an expiry date. WHMIS 2015 does not make an SDS invalid simply because it is several years old; the employer must have current information and must update the SDS when new hazard information becomes available. However, this SDS is incomplete. Section 8 should include exposure limits and exposure controls where they exist or are applicable, not just a generic instruction to use local exhaust. Section 4 should give first aid by route of exposure, such as inhalation, skin contact, eye contact, and ingestion. The employer should ask the supplier for a current, complete SDS and compare it with the 2017 version. If the supplier confirms there is no newer information, the employer still needs the missing required content corrected. The employer should not rely on an incomplete SDS merely because its date is not expired.
2. What worker education is required before the night-shift worker uses the solvent, and how should language be handled?
Read the worked answer
The employer must provide WHMIS education and site-specific training before the worker uses the solvent. The worker needs to understand the product's hazards, how to read the label and pictograms, how to handle and store the solvent safely, what protective equipment and ventilation are required, what to do in a spill or exposure, and where the SDS is kept and how to use it. A generic 10-minute video from 18 months ago is not enough for a new product and a new worker. The training must be delivered in a language and at a level the worker understands; using an interpreter, translated materials, or a competent trainer is necessary if the worker's English is limited. The employer should document the training and verify understanding, for example by having the worker locate the SDS and explain the emergency steps.
3. How should the employer respond to the dizziness and headache report?
Read the worked answer
The worker should be removed from the wash tank area and assessed by a medical professional. The employer should review the SDS first-aid and exposure-control sections, check whether ventilation is adequate, and investigate whether the work practice or equipment contributed to the exposure. The incident should be reported under the applicable OHS rules and reviewed with the joint health and safety committee or worker representative. The employer should also correct the training gap, confirm that the SDS is readily available, and consider exposure monitoring if the solvent has inhalation hazards. Returning the worker to the same task without changing ventilation, procedures, or training would leave the hazard in place.
