![]() Use of lock out, tag out protocols should be enforced to ensure that mechanical moving parts like augers do not activate and materials do not shift underneath the worker. They should have a buddy on the outside of the container and a reliable form of communication between them. Workers should not enter a container unless they are wearing a retrieval harness. ![]() If work is necessary over an open container without railings or a grate, workers should wear safety harnesses with retrieval lines. If there is no railing, there should be a grate or walkway with railings. Open containers should have a railing and toe board around them. ![]() The dangers involved include entering or falling into a confined space, a hazardous atmosphere, and/or engulfment by the materials.Įach container type at a site should be evaluated to determine if it is a confined space. Containers include storage bins, silos, vats, tanks, bunkers, and hoppers. Such operations should have an adequate number of exit ladders, daily safety inspections, and should include engineering principles such as shoring and sloping.Ĭontainers can be dangerous if workers need to enter them for maintenance or repair, or if they need to work over them to load or unclog materials. Trenches or excavation pits at construction sites pose a cave-in hazard where the collapsing soil can engulf workers. They should also be instructed on safety protocols, rescue operations, and the use of life safety equipment. Workers should be instructed on the hazards of over-sized containers and storage bins at the worksite as well as the materials kept in them. The hoist should be able to stop and hold any expected load including the impact of a fall. The hoist operator should pay out and retrieve excess line to maintain reasonable tautness. Workers should not stand, climb, or walk on piles of materials without safety equipment like a hoist with a boatswains chair or a body harness. Piles of loose granular materials pose an engulfment hazard if they shift or slide. These trenches or open pits should have an adequate number of exit ladders, daily safety inspections, and should include safety engineering such as proper shoring and sloping. A sudden release of oxygen under pressure can result in a relatively large jet of escaping oxygen. This can be particularly hazardous in areas where there is not sufficient ventilation causing the oxygen concentration to increase. Trenches or excavation pits at construction sites pose an engulfment hazard when a cave-in or soil collapse engulf a worker. Leaking pipe, flange or manifold connections. Respiratory hazards associated with engulfment includes suffocation from breathing in a fine substance that fills the lungs or from drowning in a liquid. Engulfment causes physical harm when the material has enough force on the body to cause injury or death by constriction, crushing, or strangulation. Engulfment results when a worker is surrounded and overcome by a granular substance such as soil, sand, gravel, sawdust, seed, grain or flour or if submerged in a liquid such as water or a chemical. In many worksite situations, workers are at risk for engulfment hazards.
