Industrial hygiene control

This book provides an advanced level of study of industrial hygiene engineering situations with emphasis on the control of exposure to occupational health hazards. Primary attention is given to industrial ventilation, noise and vibration control, heat stress, and industrial illumination. Other topics covered include industrial water quality, solid waste control, handling and storage of hazardous materials, personal protective equipment, and costs of industrial hygiene control.

Exposures to ethyl acrylate monomer are most likely to occur in an occupational environment via skin contact and inhalation. However, the closed systems used during manufacture and transportation will limit worker exposures to those that may occur during routine process maintenance, periodic plumbing leaks, and the collection of quality control samples. Under these conditions, exposures are further limited by the use of industrial hygiene controls and personal protective equipment. The acrid odor of ethyl acrylate, which can be detected at 0.001-0.005 ppm, also serves to limit exposure. Studies of monomer production workers have indicated that... 

Industrial Hygiene Reviews These reviews evaluate the potential of a process to cause harm to the health of people. It is the science of the anticipation, recognition, evaluation, and control of health hazards in the environment. It usually deals with chronic, not acute, releases and is involved with toxicity. 

Toxic hazards may be caused by chemical means, radiation, and noise. Routes of exposure are (1) eye contact, (2) inhalation, (3) ingestion, (4) skin contact, and (5) ears (noise). An Industrial Hygiene Guide (IHG) is based on exposures for an 8-h day, 40-h week, and is not to be used as a guide in the control of health hazards. It is not to be used as a fine hne between safe and dangerous conditions. 

The air inside a factory building can be polluted by release of contaminants from industrial processes to the air of the workroom. This is a major cause of occupational disease. Prevention and control of such contamination are part of the practice of industrial hygiene. To prevent exposure of workers to such contamination, industrial hygienists use industrial ventilation systems that remove the contaminated air from the workroom and discharge it, either with or without treatment to remove the contaminants, to the ambient air outside the factory building. 

Check the toxicity of process materials, identify short and long term effects for various modes of entry into the body and different exposure tolerance Identify the relationship between odour and toxicity for all process materials Determine the means for industrial hygiene recognition, evaluation and control Determine relevant physical properties of process materials under all process conditions, check source and reliability of data... 

LVHV nozzles can create problems that may be sufficiently severe as to prevent their use, usually in the form of ergonomic encumbrances and excessive noise. These problems can be dealt with, to limited extents, and LVHV applications can be effective. It must also be understood that dust control by 1..VHV systems is ultimately limited. No ventilation control measure can ensure sufficient worker protection down to extraordinatily low acceptable dust levels. Worker protection must always be confirmed by industrial hygiene monitoring and evaluation, and administrative control measures such as respiratory protection may be necessary. 

Industrial hygiene The science and art devoted to the anticipation, recognition, evaluation, and control of those environmental factors or stresses arising from the workplace which cause sickness, impaired health and well-being, or significant discomfort and inefficiency among workers or among the citizens of the community. 

Functions such as industrial hygiene (the protection of worker health against occupational hazards) and hazardous waste mcmagement involve the control of hazards arising from processes. As with process safety, you can attempt to use engineering-based solutions alone, but will find that ongoing control of hazards is difficult to achieve. Designing-in hazard control and... 

In Exhibit 2-8 the need for new, or modified, control programs or elements could arise either because you have introduced a new process or facility, or modified an existing one. These changes may introduce new process hazards, new occupational safety or industrial hygiene issues or new environmental concerns. Any new hazards need to be assessed so that the company can decide whether they are tolerable or require new controls to... 

All these entry routes are controlled by the application of proper industrial hygiene techniques, summarized in Table 2-1. These control techniques are discussed in more detail in chapter 3 on industrial hygiene. Of the four routes of entry, the inhalation and dermal routes are the most significant to industrial facilities. Inhalation is the easiest to quantify by the direct measurement of airborne concentrations the usual exposure is by vapor, but small solid and liquid particles can also contribute. 

Industrial hygiene is a science devoted to the identification, evaluation, and control of occupational conditions that cause sickness and injury. Industrial hygienists are also responsible for selecting and using instrumentation to monitor the workplace during the identification and control phases of industrial hygiene projects. 

The three phases in any industrial hygiene project are identification, evaluation, and control ...
