The Occupational Safety and Health Administration (OSHA) has issued a final rule to curb lung cancer, silicosis, chronic obstructive pulmonary disease and kidney disease in America's workers by limiting their exposure to respirable crystalline silica. The rule is comprised of two standards, one for Construction and one for General Industry and Maritime. This lesson is designed to improve the safety of workers in environments where silica exposure hazards exist by increasing employee awareness of this hazard and by demonstrating how the hazard can be recognized and addressed in the workplace.

To protect you from the serious hazards posed by the unexpected start-up or operation of equipment during repair or maintenance, the Occupational Safety & Health Administration (OSHA) has established a Control of Hazardous Energy standard. It is commonly referred to as the lockout/tagout (LOTO), or energy isolation standard. This standard requires the application of markings and barriers that prevent unauthorized persons from energizing and operating equipment.Energy in any form becomes hazardous when it builds to a certain level or is released inadvertently or unexpectedly. Lockout/tagout refers to specific practices and procedures that safeguard employees from the unexpected startup of machinery and equipment, or the release of hazardous energy, during service or maintenance activities.

Nuclear criticality accidents have killed, but these accidents don’t happen often because when they do occur, the results have historically proven disastrous; regulations, training, and procedural safeguards have all intensified in the wake of high-profile, fatal events around the world. Accidental criticality is a hazard unique to facilities where fissionable materials are handled or stored, such as nuclear fuel manufacturing and processing facilities. The Nuclear Regulatory Commission characterizes these events as “uncontrolled nuclear fission chain reactions.” So, that’s what we’re talking about, and unexpected, unplanned nuclear episode that poses risk to human health and wellbeing proportionate to the size of event and proximity of those exposed.
