  2. MTTFd - Wikipedia

    en.wikipedia.org/wiki/MTTFd

    The likelihood of occurrence of a dangerous or safe failure may differ and is a function of several variables in the construction and design of a component. A poorly designed switch may have a higher proportion of dangerous failures (thus a lower MTTF D ), whereas switches rated for use in safety circuits may very well preclude the occurrence ...

    en.wikipedia.org/wiki/Tire_maintenance

    Tread worn away completely: especially when the wear on the outer rubber exposes the reinforcing threads within, the tire is said to be bald and must be replaced as soon as possible. Sometimes tires with worn tread are recapped, i.e. a new layer of rubber with grooves is bonded onto the outer perimeter of a worn tire. Since this bonding may ...

  4. Hierarchy of hazard controls - Wikipedia

    en.wikipedia.org/wiki/Hierarchy_of_hazard_controls

    Employers must provide PPE when other control measures are still being developed or cannot adequately reduce hazardous exposure to safe levels. [16] Personal Protective Equipment (PPE) minimizes risks to health and safety when worn correctly, including items like earplugs, goggles, respirators, and gloves.

  5. Workplace safety standards - Wikipedia

    en.wikipedia.org/wiki/Workplace_Safety_Standards

    These standards are set of rules and describe dangerous substances in machine oils, polycyclic aromatic hydrocarbons in extender oils and other chemical materials used in workplace. The Russian standard describes the physical and chemical properties of dangerous oils.

  6. Factor of safety - Wikipedia

    en.wikipedia.org/wiki/Factor_of_safety

    In engineering, a factor of safety (FoS) or safety factor (SF) expresses how much stronger a system is than it needs to be for an intended load.Safety factors are often calculated using detailed analysis because comprehensive testing is impractical on many projects, such as bridges and buildings, but the structure's ability to carry a load must be determined to a reasonable accuracy.

  7. Occupational exposure limit - Wikipedia

    en.wikipedia.org/wiki/Occupational_exposure_limit

    It is typically set by competent national authorities and enforced by legislation to protect occupational safety and health. It is an important tool in risk assessment and in the management of activities involving handling of dangerous substances. [1] There are many dangerous substances for which there are no formal occupational exposure limits.

    The exchange rate means that when the noise level is increased by either 3 dBA (according to the NIOSH REL) or 5 dBA (according to the OSHA PEL), the amount of time a person can be exposed to a certain noise level to receive the same dose is cut in half. Exposures at or above these levels are considered hazardous.
