Respiratory protective equipment protect against environmental pollutants
Posted by admin | Cleaning, Protective Equipment | Posted on January 18th, 2011
There are three groups of respiratory hazards:
– Threat by external airway.
– Threat of the person by action through the airways.
– Health risks or discomfort associated with the use of respiratory protective equipment.
Respiratory Protective Equipment help protect against environmental pollutants reducing their concentration in the breathing zone at levels below occupational exposure limits.
Whenever in the workplace using respiratory protective equipment should be implemented a formal program of respiratory protection. This program should include identification and evaluation of contaminants. There should be special emphasis on education of personnel to use equipment, organizing training courses and by monitoring their effectiveness. They should also established maintenance programs, cleaning and storage of equipment and ensure compliance daily. Respiratory protection program and training activities must be documented so that they can be understood and consulted by all staff involved. To implement a respiratory protection program recommends taking the following steps:
1. Identify contaminants. Before choosing respiratory protective material is important to identify and quantify contaminants against which must be protected. Airborne contaminants are divided into two groups, these are: particles and gases and vapors. The particles in turn may be in the form of powder, mist or fumes. It will also be necessary to determine whether there is a deficiency of oxygen and / or extreme temperatures.
2. Understanding the effect of pollutants on health. Once identified contaminants is necessary to understand how they can affect the human body if inhaled. This information is a vital part of training to be provided to computer users, enabling them to understand the reasons why you should use the equipment they have available.
3. Select the team of respiratory protection appropriate. Should always be made by a person who knows the working conditions and benefits and limitations of protective equipment.
4. Train workers in the use and care of equipment. Once a respiratory protective equipment has been properly selected is essential to train the user on the proper fit, use, maintenance and care of equipment. It is also important to demonstrate placement practices and methods to check face fit, so that the worker is adequately protected.
Features & benefits of using protective respirators:
There is an ideal equipment for all types of pollutants. Here is an overview of the instructions and limitations, but you should always check the packaging and instruction booklet carefully for specific information:
PPE designed to protect the respiratory tract must allow the user with breathable air when exposed to a polluted atmosphere and / or a concentration of oxygen is insufficient. Protection against contaminants is obtained by reducing their concentration in the breathing zone below the recommended exposure levels. The degree of tightness of the face piece and the pressure drop on inspiration and, in the filtering devices, purification capacity must be such that in a polluted atmosphere, the penetration of pollutants is low enough to avoid damaging health or hygiene of the user.
If there is potential for oxygen deficiency, measure the oxygen content of the workspace in question. The type of respiratory protective equipment that can be used depend on the partial pressure of oxygen. As the only air purifiers clean the air, there must be enough oxygen in the atmosphere to sustain life.
Misuse of equipment can result in overexposure to the contaminant and cause an accident or occupational disease. Therefore, to ensure adequate protection is necessary to select the correct respirators, and train users in proper use and maintenance.
