An initial site evaluation may be required due to an illness, spill, or accident. This evaluation may be a proactive measure, or may be required by regulation in an uneventful industrial setting.
Workplace exposures occur under many circumstances. Identifying these exposures involves recognition of causes.
If they are chemical, biological, or physical hazards, DirectCIH industrial hygiene teams arrive on site, rapidly if necessary, to investigate.
Knowledge of processes, observation, and measurement with instruments is conducted. Chemical hazards such as fuels, chemical intermediates, or aerosols require assessment and investigation of areas where levels are highest.
Biological hazards such as mold, bacteria, viruses, endotoxins, or antigens require focus on controlling pathogen transmission, especially in air. Exposed individuals are assigned risk groupings based on National Institutes of Health (NIH) guidelines.
Where hazards are physical in nature, specific solutions must be found. Included are agents such as heat, noise, radiation, and electricity, and also working conditions involving working surfaces, high work, confined spaces, and excavations.
Field measurements determine the amount and extent of hazard produced by an agent. Process descriptions, observations, and other information is then used in assembling an exposure assessment program.The program is then used to develop:
- Effective engineering controls
- Administrative controls
- Work practices, and/or
- Personal protective equipment.
Identifying the need for and proper implementation of controls include the following evaluations: ventilation systems, process changes, material substitution, or the time of day or way a task is accomplished. The evaluation methods employed by DirectCIH effectively reduces exposures.
Industrial processes that involve the use of chemicals, or are associated with physical hazards, can be assessed using both on-site and laboratory monitoring techniques. DirectCIH has many direct-reading instruments and long experience in acquiring solid data quickly.
We have long standing associations with the best AIHA accredited labs and working relationships with their personnel. These methods allow us to conduct industrial monitoring for normal operations, spill or accident situations, or at workplaces where unknown exposures impair the health of those present.
Gas chromatography, mass spectroscopy, infrared spectroscopy, and chemical sensors are used on-site to determine types and amounts of airborne chemicals. Electronic dosimetry and octave band analysis are used on-site to assess noise.
Dust, metals, silica, nanoparticles, and other aerosols are quantified on-site using laser photometry for mass determinations and particle counts. Thermal imaging, radiation detection, moisture detection, vibration and heat stress measurement, and anemometry are other on-site monitoring capabilities.
Whether you need a one-time determination, time-weighted average or long-term assessment, DirectCIH is prepared for your industrial monitoring needs.
The types and amounts of hazardous waste generated, processed, stored, and transported at a facility has a significant bearing on assessing worker exposure.
Hazardous waste is closely controlled under EPA regulations as well as under OSHA, since many Subpart Z chemicals are hazardous waste.
DirectCIH has an extensive working knowledge of these regulations, including determination and methods of minimization, substitution, removal, and reduction of hazardous waste from stringent regulatory requirements.
Exposures from waste streams can be significantly reduced when these methods are used, saving money and improving worker health and productivity.
Exposure assessments for personnel are a successful strategy to reduce worker health risk, improve compliance and make management easier.
