A licensed contractor installed two newly manufactured vertical machine-mounted air receivers for instrument air processes at a wood treatment facility in November 2020. During a scheduled maintenance service after eight months of operation, cracks were located on the top head of each vessel, specifically at the head-to-bracket weld fillet welds. The cracking was in similar […]
This ammonia refrigeration system for the ice rink had been shut down, and the full ammonia charge (800 pounds) was being stored in the chiller, attached surge vessel, and the oil pot. Three (3) days before the incident, a contractor was doing maintenance on the brine system to install a pH sensor in the brine
Last month CAL-OSHA issued a revised guide on Controls for Hazardous Energies. This is a MUST-HAVE for all safety professionals responsible for their Lockout/Tagout (LOTO) Program. Never mind that it is a State OSHA program publication – this is a solid document that explains the in’s and out’s of LOTO. My favorite section… Interlocks Are
WHY OIG CONDUCTED THE AUDIT The Occupational Safety and Health Administration (OSHA) is responsible for ensuring safe and healthful working conditions for 130 million workers employed at more than 8 million worksites. It does so by setting and enforcing standards and by providing training, outreach, education, and assistance to employers and employees. The COVID-19 pandemic
The Chemical Facility Anti-Terrorism Standards (CFATS) program requires high-risk facilities to ensure security measures are in place to reduce the risk of more than 300 chemicals of interest (COI) being weaponized. High-risk facilities are assigned to one of four (4) risk-based tiers and must develop a security plan meeting the 18 Risk-Based Performance Standards (RBPS).
MINE FATALITY – On October 7, 2022, a mechanic was fatally injured when engulfed in the material after entering an air separator to clear a blockage. Best Practices
Last week I wrote about how either distance or a barrier is necessary to CONTROL hazards. OSHA’s made a great case in 2020, explaining how the separation distances in 1910.110 is a PASSIVE MITIGATION measure. (emphasis by me) OSHA concludes that NFPA 58 (2017), Sections 6.28.2 and 6.28.3, do not provide an equivalent level of
Recently a trade organization issued a guide on working in Permit Required Confined Spaces specific to their industry. The organization took a sentence from NFPA’s Guide on Confined Spaces (NFPA 350) and used it as justification to circumvent OSHA’s minimum standard on entry into PRCSs (1910.146 and 1926.1201-.1213). l have received over a dozen questions
As stated in REGO’s Warning Document… Simply retesting pressure relief valves manufactured by RegO that have been in service for several years to confirm conformance with start-to-discharge and reseal ranges does NOT guarantee that the valve is suitable for continued service. Or that the valve will perform as designed at nominal pressures or in emergency
“Relief valves should be inspected each time the container is filled but no less than once a year. If there is any doubt about the condition of the relief valve, it must be replaced.” Major Factors to determine the “Life” of Relief Valves include: Water/Ice Accumulation Corrosion Dirt – Debris Damage Normal Aging Eye protection
The old debate has been settled by the largest provider of LEVEL A suits. Many organizations store their emergency response gear in a trailer that is parked (usually) outside on the property. Although OSHA does not mention this level of detail, the manufacturer has now established the maximum temperature at which their suits may be
In a recent discussion regarding an accident with a Fuel-Oxy Torch system, I had some discussions about the layers of protection and the Prevent-Protect-Mitigate safety model using the Hierarchy of Controls (Elimination, Substitution, Engineering Controls, Administrative Controls, and PPE). The event did NOT involve a flash-back, but I used the flash-back requirements to demonstrate the
