What are some general types of engineering controls?
Engineering measures include: • local and general exhaust ventilation; • enclosure/encapsulation; • material substitution; • component replacement with new components; • process and equipment modification; and • isolation or automation. What are examples of the recommended engineering control “local and general exhaust ventilation ?” Power tools used for the removal of lead-based paint should be equipped with dust collection shrouds or other attachments exhausted through a high-efficiency particulate air (HEPA) vacuum system. Operations such as welding, cutting/burning and heating should be provided with local exhaust ventilation. Vacuums should be equipped with HEPA filters if they are used during clean-up activities. For abrasive blasting operations where full containment exists, the containment structure should be designed to optimize the flow of ventilation air past the worker(s), so that the airborne concentration of lead is reduced and the visibility is increased.
