Currently, the Occupational Safety and Health Administration, OSHA, has two main enforcement programs that affect the concrete industry. They are referred to as Regional Emphasis Programs, or REP's:
1) SIC Code 34 (fabricated metal products) - a complete list of SIC 34 businesses in each region is provided to the regional OSHA office by OSHA national. This list is assigned a random order, and the facilities are inspected in that random order. These inspections include any hazard to employees, which is primarily hazardous chemicals, machine guarding, lock-out/tag-out, cranes, and other material handling. SIC 34 includes fabricated structural steel (beams, columns, pipes), bar joists, concrete reinforcing bars, and fabricated wire products. If your company files any labor, employment, or tax reports using an SIC 34 (including sub-codes 34x and 34xx), you are on this list.
2) Construction - any work or workplace condition which is visible from a road or other public place and is unsafe can trigger a full worksite inspection. The "big four" are falls, struck-by, caught-in, and electrical hazards. Once they are on site for these hazards, anything they see will be addressed (and possibly cited.)
