Personal safety devices effectiveness

Respiratory Protection To assess the safety of any particular operation, measurement of the solvent vapor exposure to workers in the area is recommended. If it is determined that the concentration in air is less than the recommended TWA for the solvent, no injury would be expected to workmen. If changes are made in the operation, which may result in an increase in concentration, duration, or frequency of exposure, measurements should be repeated. The degree of hazard can be minimized by containing the cleaning operation in an enclosed area, such as a hood, by ventilation that removes the vapors from the workroom air away from workers. The use of personal protective devices, such as gas masks, respirators, and self-contained or remote breathing apparatus, are not recommended for continuous use but can be effective for handling spills or similar upsets. 

In a plant, a circuit breaker is a passive safety device. The electric current, the motor, the load, and the circuit breaker determine when the current is to be interrupted. There is no worker standing by to evaluate the motor and then break the circuit. Effectiveness depends on correct installation and maintenance, not personal intervention. 

If an alarm system is to be effective, it must be used, tested, and maintained according to strict policy. Any personal alarm devices should be carried and tested as required by the manufacturer and facility policy. Maintenance on personal and other alarm systems must take place monthly. Batteries and operation of the alarm devices must be checked by a security office to ensure the function and safety of the system. Any mechanical device used for security and safety must be routinely tested for effectiveness and maintained on a scheduled basis. 

Adverse Incident Reporting is an essential part of POC management and important to post-market regulation surveillance. Adverse incidents include any event that causes, or has the potential to cause, unexpected or unwanted effects involving the safety of device users including patients or other persons [Medicines and Healthcare Products Regulatory Agency (MHRA)] and reports should be made to the relevant local bodies [48]. 

A lot of thinkable applications help men on many occasions. Sensors that detect data correlating to physical body functions (e.g., pulse, temperature) offer comfort and safety. Even visual aids for amaurotics may be common devices in medical science in a few years. Information would be transmitted from the sensor through the textile, which then stimulates the cutaneous nerves. Textile sensors can serve meaningfully in the monitoring of hazard areas, infirm or chronically sick persons and sportspersons. Soft sensors are textile piezoelectric resistor-sensors for the detection of movement and respiration. The piezoelectric effect can be enforced by exterior mechanical influences. They add importance to the functional textiles. 

Numerous security devices may reduce the risk for assaults against workers and facilitate the identification and apprehension of perpetrators. These include closed-circuit cameras, alarms, two-way mirrors, card-key access systems, panic-bar doors locked from the outside only, and trouble lights or geographic locating devices in taxicabs and other mobile workplaces. Personal protective equipment such as body armor has been used effectively by public safety personnel to mitigate the effects of workplace violence. For example, the lives of more than 1800 police officers have been saved by Kevlar vests.
