Translate into Japanese "Another step in recognizing health hazards is to know if there are occupational exposure limits or restrictions for the hazardous products identified in your chemical inventory. By recognizing these hazards, employers can implement control measures such as engineering controls, administrative controls, or PPE to mitigate the risks and protect the health and safety of workers.

3. Evaluation of Exposure
Evaluation of exposure is the third principle in industrial hygiene. After anticipating and recognizing your health hazards, it’s time to evaluate the risk of exposure through an Occupational Exposure assessment. This assessment is crucial determining whether the exposure levels are within acceptable limits and if additional control measures are needed to minimize risk. It typically involves the collection of data through various methods such as air sampling, personal monitoring, and biological monitoring.

Due to the complexity of the work environment and the measuring instruments, monitoring should only be done by a qualified professional like an industrial or occupational hygienist.

Industrial Hygiene Monitoring
Industrial hygiene monitoring captures the exposure level of a certain population of workers during their work activities at a certain time. This measurement can be conducted on those with the highest potential exposure, or a representative exposure, measurements can also refer to a similar exposure group (SEG), workers who perform the same tasks at the same frequency, with similar materials.

Industrial hygiene monitoring measures a specific physical, biological or chemical agent where the exposure occurs. Monitoring also needs to consider variations in exposure during different work shifts or facility maintenance activities like turn arounds. Monitoring will have a defined purpose or question it is trying to answer. Generally, it is trying to determine if exposures are safely below or over the occupational exposure limits (OEL) for the hazardous product.

Qualitative and quantitative analysis of data from monitoring is used to determine if exposure results are acceptable, unacceptable, or uncertain. Coming to this conclusion requires a knowledge of the occupational exposure limit in the jurisdiction in which you are operating. OELs for long-term and short-term exposure to a hazardous substance vary by province, state, and country.

Not all substances in commerce have OELs developed for them.

4. Control Over Worker Exposure
Controlling worker exposure is the next principle of industrial hygiene. It refers to the concept of implementing measures to minimize or eliminate workers’ exposure to hazardous substances in the workplace when hazardous exposure is determined to be unacceptable. The hierarchy of controls should be used to guide decisions on a multifaceted approach to exposure control. Although people instinctively think of Personal Protective Equipment or PPE first, it should be the last control applied once elimination, substitution, engineering controls and administrative practices are considered.

5. Confirmation of Control Measures
Confirmation of control measures is the last principle of industrial hygiene. This step highlights the importance of assessing the performance of hazard control measures and subsequent worker exposures. Investigating existing or potential issues and applying corrective actions is also part of confirming that your industrial hygiene program is effective. Maintaining data and reports is also key to track and trend the success of your industrial hygiene program to prevent injury, illness, or negative effects to the well-being of workers.

By implementing such an industrial hygiene program that is based on all 5 industrial hygiene principles, companies can identify and control potential occupational hazards, thereby reducing the risk of workplace injuries and illnesses. This not only protects the well-being of employees but also helps to maintain a productive workforce.

Develop an Industrial Hygiene Program with CHAMP
The principles of industrial or occupational hygiene are dynamic and require continual evaluation and reassessment as new hazards are introduced to the workplace and facilities change. Following these principles will protect a workplace’s most valuable asset: its people. Chemscape’s Chemical Hazard Assessment Management Program, also known as CHAMP, has the tools to help you identify and effectively manage the chemical hazards in your workplace.”"
