Applying this principle to occupational surveillance exams, a PLHCP may judge that certain surveillance exams are not needed urgently, because they are aimed primarily at detecting chronic health problems that may arise slowly over months-to-years. In these situations, the risk of potential COVID exposures during a face-to-face encounter may outweigh the likely medical benefit, especially since COVID is often spread by persons with no symptoms.
Certain medical procedures, such as spirometry or audiometry in a closed hearing booth pose an especially high risk of exposing both patients and medical staff to infectious droplets or aerosols. A Uses of hazardous chemicals which do not meet the definition of laboratory use, and in such cases, the employer shall comply with the relevant regulations in Title 8, California Code of Regulations, even is such use occurs in a laboratory.
B Laboratory uses of hazardous chemicals which provide no potential for employee exposure. Examples of such conditions might include:. Procedures using chemically-impregnated test media such as Dip-and-Read tests where a reagent strip is dipped into the specimen to be tested and the results are interpreted by comparing the color reaction to a color chart supplied by the manufacturer of the test strip; and.
Commercially prepared kits such as those used in performing pregnancy tests in which all of the reagents needed to conduct the test are contained in the kit. Action level. A concentration designated in Title 8, California Code of Regulations for a specific substance, calculated as an eight 8 -hour time weighted average, which initiates certain required activities such as exposure monitoring and medical surveillance.
Chemical Hygiene Officer. An employee who is designated by the employer, and who is qualified by training or experience, to provide technical guidance in the development and implementation of the provisions of the Chemical Hygiene Plan. This definition is not intended to place limitations on the position description or job classification that the designated individual shall hold within the employer's organizational structure. Chemical Hygiene Plan. A written program developed and implemented by the employer which sets forth procedures, equipment, personal protective equipment and work practices that.
Designated area. A designated area may be the entire laboratory, an area of a laboratory or a device such as a laboratory hood. Any occurrence such as, but not limited to, equipment failure, rupture of containers or failure of control equipment which results in an uncontrolled release of a hazardous chemical into the workplace. An individual employed in a laboratory workplace who may be exposed to hazardous chemicals in the course of his or her assignments.
Hazardous chemical. Any chemical which is classified as health hazard or simple asphyxiant in accordance with the Hazard Communication Standard Section Health hazard. A chemical that is classified as posing one of the following hazardous effects: Acute toxicity any route of exposure ; skin corrosion or irritation; serious eye damage or eye irritation; respiratory or skin sensitization; germ cell mutagenicity; carcinogenity; reproductive toxicity; specific target organ toxicity single or repeated exposure ; aspiration hazard.
It is a workplace where relatively small quantities of hazardous chemicals are used on a non-production basis. Laboratory scale. Work with substances in which the containers used for reactions, transfers, and other handling of substances are designed to be easily and safely manipulated by one person. Laboratory-type hood. A device located in a laboratory, enclosed on five sides with a movable sash or fixed partial enclosure on the remaining side; constructed and maintained to draw air from the laboratory and to prevent or minimize the escape of air contaminants into the laboratory; and allows chemical manipulations to be conducted in the enclosure without insertion of any portion of the employee's body other than hands and arms.
Walk-in hoods with adjustable sashes meet the above definition provided that the sashes are adjusted during use so that the airflow and the exhaust of air contaminants are not compromised and employees do not work inside the enclosure during the release of airborne hazardous chemicals.
Laboratory use of hazardous chemicals. Handling or use of such chemicals in which all of the following conditions are met:. Medical consultation. A consultation which takes place between an employee and a licensed physician for the purpose of determining what medical examinations or procedures, if any, are appropriate in cases where a significant exposure to a hazardous chemical may have taken place.
Chemicals that cause permanent changes in the amount or structure of the genetic material in a cell. Chemicals classified as mutagens in accordance with the Hazard Communication Standard Section shall be considered mutagens for purposes of this section. Physical hazard. A chemical that is classified as posing one of the following hazardous effects: Explosive; flammable gases, aerosols, liquids, or solids ; combustible liquid; oxidizer liquid, solid, or gas ; self-reactive; pyrophoric gas, liquid or solid ; self-heating; organic peroxide; corrosive to metal; gas under pressure; in contact with water emits flammable gas; water-reactive; or combustible dust.
Protective laboratory practices and equipment. Those laboratory procedures, practices and equipment accepted by laboratory health and safety experts as effective, or that the employer can show to be effective, in minimizing the potential for employee exposure to hazardous chemicals. Reproductive toxins. Chemicals which affect the reproductive capabilities including chromosomal damage mutations , effects on fetuses teratogenesis , adverse effects on sexual function and fertility in adult males and females, as well as adverse effects on the development of the offspring.
Chemicals classified as reproductive toxins in accordance with the Hazard Communication Standard Section shall be considered reproductive toxins for purposes of this section. Select carcinogen. Protect Yourself - Spirometry Breathing Test. Standards Medical screening and surveillance are addressed in specific OSHA standards for general industry. Medical Screening Provides information about medical screening and clinical evaluation.
Medical Surveillance Provides resources that contain medical surveillance information including specific hazards and surveillance guidelines. Additional Resources Provides links and references to additional resources related to first aid.
