What 29 CFR 1926.702 requires (plain English)
29 CFR 1926.702 sets the equipment-specific safety requirements for concrete construction, covering bulk cement storage, concrete mixers, power concrete trowels, buggies, pumping systems, and concrete buckets. These machines handle heavy material overhead, under pressure, and at speed, so the standard prescribes guards, latches, and controls for each.
A central requirement is that concrete buckets equipped with hydraulic or pneumatic gates have positive safety latches or similar devices to prevent premature or accidental dumping. Concrete mixers with one-cubic-yard-or-larger loading skips must have mechanical guards and operator-protection devices; concrete pumping systems must have their hoses secured and their systems designed and operated to control the pressure; and bulk cement storage must be guarded.
1926.702 works with the general concrete standard (1926.701), which keeps workers clear of buckets and equipment, and the formwork standard (1926.703). Together they address the placement phase of concrete work, when heavy equipment and fresh material create struck-by, caught-in, and pressure hazards.
