Frequently asked questions about health and safety tend to focus on the considerations that need to be taken into account in specific working environments. Examples include: "How do I protect myself when I have to work outside in extreme cold?"; "What workplace precautions should be taken to reduce the spread of flu?"; and "How do I dispose of bloodborne pathogens?" according to the official website for the Occupational Safety & Health Administration (OSHA). Some questions also center on how to adhere to guidelines set by this government body, such as "Must crane inspectors be certified?"
Tips for protecting the body against cold stress when working outdoors in extreme weather conditions are provided elsewhere at the OSHA website. These are intended to help employees in such working conditions avoid health issues such as trench foot, frostbite and hypothermia.
Likewise, the OSHA website has a whole section devoted to reducing the spread of flu. Bloodborne pathogens should be placed in closable, labeled containers designed to prevent leakage, as directed at the OSHA website. If that container is contaminated from outside, it should be placed inside a second container of the same kind.
The answer to the question on guidelines for crane inspectors is that they do not need to be certified. Their qualification for the job is based instead on expertise.
