The employer must classify each lead process as either reasonably likely or not reasonably likely to cause employees' blood lead levels to exceed the r 193 thresholds. In doing so it must consider employees' past biological monitoring results, whether airborne lead exceeds half the lead exposure standard, the form of lead used, the specific tasks or processes, how often and how long exposure is likely to occur, possible exposure routes, and any information on lead-related incidents, illnesses or diseases at the workplace. The protective effect of personal protective equipment must be left out of the assessment. Where the employer cannot decide, the process is treated as lead-risk work until it establishes otherwise. The duty supports section 21 of the Act.
