The hierarchy of controls is a systematic approach used to minimize or eliminate workplace hazards. This section explains each level of control, including elimination, substitution, engineering controls, administrative controls, and personal protective equipment. Learn how to apply these methods effectively to reduce risks and improve safety performance in different work environments.
TL;DR I was walking a fabrication shop floor during a noise exposure assessment when I noticed a bench grinder running at full speed with its wheel guard removed. The operator was wearing ear plugs — the foam kind, half-inserted — and no face shield. When I stopped the job and asked the supervisor why the … Read more
TL;DR I was reviewing a confined space fatality investigation file from an oil refinery turnaround when the root cause summary stopped me cold. The permit-to-work procedure existed. The gas testing protocol was documented. The entry log template was printed and laminated, hanging right next to the manhole. Every administrative control was technically “in place.” But … Read more
TL;DR I was reviewing a contractor’s risk assessment for a grinding operation inside a fabrication shop — a routine pre-task audit on a large EPC project in the Gulf. The assessment identified respirable metal dust as the primary hazard. Under “control measures,” three items were listed: dust masks, safety briefing, and a generic work instruction. … Read more
Noise is an often-overlooked occupational hazard that can seriously affect health and productivity. Whether it’s the constant hum of machinery, the roar of heavy equipment, or high-decibel construction tools, prolonged exposure to excessive noise can lead to hearing loss, tinnitus, stress, and even reduced workplace safety. This underscores the importance of implementing robust noise risk … Read more
Working at height is one of the most hazardous activities in many industries, from construction and maintenance to telecom and warehousing. Every year, numerous accidents and fatalities occur due to falls—most of which are preventable by adhering to essential requirements for working at heights. This is where the Hierarchy of Control for Height Work comes … Read more
