Final answer:
Under WHMIS 1988, partially exempted items may not need a full Material Safety Data Sheet or complete labeling, but employers are obliged to provide proper training on their safe use. Such items must be communicated regarding their name, hazards, precautions, and first-aid measures, although they may still be regulated under other laws.
Step-by-step explanation:
The question refers to the requirements for partially exempted items under the Workplace Hazardous Materials Information System 1988 (WHMIS 1988). Under this system, certain partially exempted items may not require a full set of Material Safety Data Sheets (MSDS) or fully labeled items. However, the employer still needs to ensure proper worker education and training on the safe use of these materials. This can include information about the product's name, potential hazards, safety precautions, and first-aid measures. It is important to note that while some items might be exempt from the full requirements, they might still fall under other regulations and thus require some form of hazard communication. With WHMIS transitioning into WHMIS 2015 which incorporates the Globally Harmonized System (GHS) for classification and labeling of chemicals, the information for partially exempted items might change, and it is necessary to consult up-to-date resources for current regulations.
