Engineering Controls

Engineering controls are ways of preventing rather than simply mitigating exposure. These controls are often the best way to keep employees safe. Every situation is different, though, so 8 CCR 1532.1 does not mandate any specific controls. Rather, it requires employers to analyze each situation and choose the controls that will help the most.

Isolation and Ventilation: Power tools used to remove lead paint can often include attachments that collect the dust, sending it through a high-efficiency particulate air (HEPA) filter. Local exhaust ventilation systems can help increase the flow of clean air and maintain visibility. For abrasive blasting, a containment structure can keep other areas free of dust. The containment structure itself must be ventilated, and should be fitted with a dust collection system.

Substitution: Sometimes, using different methods or equipment can help reduce exposure. The most effective example of this is using zinc-based paint instead of lead paint, but there are other means of substitution as well. Using hydraulic shears instead of torch cutting can help in some circumstances. To cut down on dust, a chemical stripper can be used instead of abrasive blasting, although chemical strippers present their own health hazards and must be treated with care.

There are many more possible engineering controls, but ultimately it is up to the employer to study and choose the controls best suited for the particular job.
