Yes, respirators will be the primary PPE discussed when protecting workers against silica dust exposures. Silica dust often arises when workers are cutting, crushing, drilling, grinding or otherwise disturbing material that might loosen silica, particularly in construction and mining work. That kind of work – cutting into concrete, brick and block, stone and rock, masonry and tile – very often requires goggles or safety eyewear with side shields to protect eyes from flying particles. Also hearing protection in many cases will be required due to high noise levels.
OSHA is proposing two new silica standards: one for general industry and the maritime industry, and one specifically for construction.
