Personal safety devices types

The next priority in the sequence is to provide safety devices, or features that prevent people from being exposed to a hazard. Safety devices are automatic and require no action on the part of a person. Safety devices do not ehminate hazards. Examples of safety devices are interlocks, dead-man switches, guards, fences, automatic fire doors, some types of fire sprinklers, and automatic air brakes that activate when there is a break in an air line. A significant problem with many safety devices is that people intentionally disable them and fail to reinstall or activate them after service or maintenance. 

Several technologies able to be used for the development of communicative textile devices have been presented. Some of them are already used for the development of textile displays. Their emission of reflective characteristics allow their use for different types of applications. Emissive devices such as luminescent stmctures or optical fibres are preferred for high-visibility outfits for personal safety, for art and fashion design or for advertising events. Reflective devices offer a softer, more discreet colour change, which could preferentially be used for everyday applications such as communicative clothes, home furnishings or fashion. 

The ground fault interrupt device, on the other hand, is designed for personal protection however, it is not infallible and cannot be depended upon for total personal safety. Also, it is used in conjunction with a circuit breaker and only for a specific type of electrical hazard, which we will see below. To understand the problem, let s examine how circuit breakers and GFI devices work. 

Considerable variety is available in the types, styles, and applications of eye and face protection. For the conditions which exist in most chemical storage facilities, where packaging remains sealed, eye protection will be dictated by the presence of physical hazards. Many warehouse operators require safety spectacles in warehouse and maintenance areas. Persons who wear prescription lenses should wear protective eyewear fitted with prescription lenses or protective devices worn over prescription eyewear. 

Personal Protective Equipment (PPE)—Any type of clothing or device that puts a barrier between the worker and the hazard (e.g., safety goggles, gloves, boats, hard hats, and so on). 

Since a PAAP type of unit wUl permit entry into an IDLH atmosphere, assuming all other personal protective equipment is suitable, the user should be aware of a number of essential safety practices associated with this use. At leastone standby person with the proper equipment for entry and rescue must be present outside the affected area. Communications must be continuously maintained between the worker within the area and the standby person. Persons within the area must be equipped with devices such as harnesses and safety lines to facilitate rescue operations should they be necessary. 

Employers can select fall protection measures and equipment compatible with the type of work being performed. Fall protection can generally be provided through the use of guardrail, safety net, personal fall arrest, positioning device, and warning line systems.
