Definitions

Action Level ‐ A concentration typically one half the published, allowable limit (such as OSHA PEL or the ACGIH TLV) that triggers certain provisions defined by the applicable regulation. It must be implemented to further reduce exposures such as applying additional exposure controls, employee training, or medical monitoring.

Area IH Sample ‐ A sample collected in a work area for the purpose of assessing the air quality in the area where employees are working or will need to work.

Carcinogen ‐ A chemical classified by the IARC as Group 1 or 2A. A product will be assumed to present a carcinogenic hazard if it contains a carcinogen in concentrations of 0.1% or greater (by weight or volume, as applicable). Consumer products containing unregulated carcinogens used in a manner similar to that of normal consumer use are exempt.

Dilution Ventilation ‐ Ventilation systems that dilute contaminated air in a whole building or room by blowing in clean air and exhausting some dirty air. Fans, blowers, and other devices designed to move available air provide dilution ventilation.

Hazardous Materials ‐ Any substance or chemical that is a health hazard or physical hazard, including, chemicals that are carcinogens, toxic agents, irritants, corrosives, and sensitizers; agents that act on the hematopoietic system; agents that damage the lungs, skin, eyes, or mucous membranes; chemicals that are combustible, explosive, flammable, oxidizers, pyrophoric, unstable‐reactive, or water‐reactive; and chemicals that in the course of normal handling, use, or storage may produce or release dusts, gases, fumes, vapors, mists, or smoke that may have any of the previously mentioned characteristics. Also includes any item or chemical that can cause harm to people, plants, or animals when released by spilling, leaking, pumping, pouring, emitting, emptying, discharging, injecting, escaping, leaching, dumping, or disposing into the environment.

Industrial Hygiene‐ That science and art devoted to the anticipation, recognition, evaluation, and control of those environmental factors or stresses arising in or from the workplace, which may cause sickness, impaired health and well‐being, or significant discomfort among workers or among the citizens of the community.

IHBHA ‐ An IHBH is a document that systematically identifies and qualitatively assesses the potential for occupational exposure to chemical, physical, and biological hazards.

LEV ‐ Ventilation systems that capture contaminate emissions at or very near the source and exhaust them outside or away from employees.

Personal IH Sample ‐ A sample collected in an employee’s breathing zone, in front of and within 12 inches of an employee’s nose, for the purpose of assessing the air quality that an employee is breathing. Personal IH samples are sometimes referred to as lapel samples.

TLV ‐ TLVs are guidelines (not regulatory requirements) prepared by the ACGIH. A TLV reflects the level of exposure that the typical employee can experience without an unreasonable risk of disease or injury.

  • Identification of the need for confirming exposure monitoring
  • Identification of follow‐up actions to be performed, including confirming exposure monitoring, development of monitoring plan(s), evaluations, and assessments

 

Industrial Hygiene Exposure Monitoring

IH Sampling Plan

An IH sampling plan will be developed based on the results of the baseline hazard assessment for each potential exposure.  The plan will specify sufficient sampling such that, when completed, an accurate exposure determination can be made.

Sample collection and analysis will be performed using recognized methods, such as the NIOSH Analytical Methods, OSHA Sampling Guide and AIHA approved IH laboratories or equivalent.

Sample collection will be performed by trained personnel, under the direction of an industrial hygienist.

IH sample results will be interpreted by comparing the applicable published, allowable exposure limit.

All IH sample results will be retained on the site in an easily retrievable manner.

Communication of Results

Employees will be notified of the results of monitoring for hazardous substances.

Notification is the dual responsibility of the contractor line management and HSE Representative.

The supervisor (line management representative), will notify the employee of the monitoring results.

When notification of an employee cannot be made due to job completion, release of the employee, or other unavailability, the supervisor will document the unavailability of the employee .

If a potential overexposure is confirmed, the employee will be notified.

The notification must identify the date of exposure, the area, and the specific hazard or airborne contaminant(s).  The notification must also include controls (engineering, administrative, and personal protection) in use at the time, and the controls that are being implemented to reduce or eliminate similar exposures (corrective actions), and (if one exists) refer in the notice to a document that states the controls/actions to be taken.

Monitoring notification forms will be maintained at the site until such time as they may be permanently stored.  These monitoring forms will be treated as confidential medical documents.

Chain of Custody

Site  or contractor HSE Representative will maintain “chain of custody” requirements and document IH sample collection in accordance with applicable regulatory requirements.

Occupational Medical Surveillance

An assessment of the need for medical surveillance will be performed predicated on the results of the baseline hazard analysis, monitoring results, and review of applicable regulations.  Employees required to be placed in a medical surveillance program will have an “employee job task/potential exposure analysis” developed based on their activities/expected activities, and transmitted to the medical surveillance provider for use in developing appropriate surveillance procedures.
