1 INDUSTRIAL HYGIENE – METHODS OF CONTROL UNIVERSITY OF HOUSTON –DOWNTOWN CAMPUSFALL 2014
2 DEFINITIONIndustrial Hygiene (IH) is that science devoted to the anticipation, recognition, measurement, evaluation, and control of adverse stresses or agents which could cause sickness and impaired health among workers and the community. The basic goal of IH is to promote a safe and healthful work environment.
3 IH ELEMENTSAnticipationRecognitionEvaluationControl
4 RECOGNITIONDetailed information to be obtained regarding types of hazardous materials used, type of job operation, worker exposures and patterns, levels of air contaminants, exposure duration, control measures, etc. Consult product information including MSDSs.
5 EVALUATIONInvolves monitoring and analytical methods required to detect the extent of exposure; decision-making process resulting in an opinion on the degree of health hazard that exists; extent of potential health hazards based on comparisons of environmental measurements with current governmental regulations and recommended guidelines.
6 CONTROLInvolves the reduction of environmental stresses to levels that the worker can tolerate without impairment of health or productivity; various general control methods employed.
7 CONTROL METHODSEngineering – remove the hazard; should be considered first. Administrative – reduce exposures through scheduling; also included is employee training; not generally favored. Personal Protective Equipment (PPE) – use should be secondary to engineering.
8 ENGINEERING CONTROLS Substitution Change in process Isolation EnclosureWet methodsVentilationGeneralDilution
9 ADMINISTRATIVE CONTROLS Examples: - Arranging work schedules and the related duration of exposure to limit employee exposures to health hazards. - Transferring employees at PELs to an environment where no additional exposure will be experienced. - Housekeeping
10 ADMINISTRATIVE CONTROLS Administrative controls must be designed only by knowledgeable health and safety professionals, and used cautiously. Not as satisfactory as engineering controls and have been criticized as a means of spreading exposures instead of reducing or eliminating the exposure.
11 PPEPPE may be used to protect the worker when it is not feasible to render the working environment completely safe. This is considered a secondary control method to engineering and administrative controls and should be used as a last resort.
12 EFFECTIVE IH PROGRAMApplies knowledge to the anticipation and recognition of health hazards arising out of work operations and processes, evaluation and measurement of the magnitude of the hazard based on past experience and study, and control of the hazards.

19 FEDERAL REGULATIONSOccupational Safety and Health Act Enacted on December 29, 1970 Effective on April 28, 1971 Purpose: “assure so far as possible every working man and woman in the nation safe and healthful working conditions and to preserve out human resources.”
20 OHS GOALPrevent occupational injury and illness by anticipating, recognizing, evaluation, and controlling occupational health and safety hazards.
21 VITAL COMPONENTSEffective health and safety program is the commitment of Senior Management and Line Management.Includes visible involvement; assignment of authority as well as the responsibility to carry out the health and safety program.

24 INDUSTRIAL HYGIENISTIndustrial Hygienists are occupational health professionals concerned primarily with the control of environmental stresses or occupational health hazards that arise as a result of or during the course of work.
25 SAFETY PROFESSIONALSpecialized knowledge in the physical and social sciencesUnderstand factors contributing accident occurrence along with motivation, behavior and communication to control safety hazardsPotential combination of IH and Safety positions due to relatively common responsibilities
26 OCCUPATIONAL HEALTH NURSE Key to delivery of comprehensive health care services to workersFocused on promotion, protection, and restoration of workers’ health within the context of the work environmentCritical link between employee’s health status, work process, and the determination of employee ability to do job.Case management approach to return injured employees to work on a timely basis
27 OCCUPATIONAL PHYSICIAN Goal is to prevent occupational illness and when illness occurs, to restore employee health within the context of a health and safe workplaceRegulations require medical surveillance programs with specific criteriaDetermination of work-relatedness of disease
