OSHA LABORATORY STANDARD & CHEMICAL SAFETY

OBJECTIVES• To become familiar with the requirements of

the OSHA Laboratory Standard and components of Tulane’s Chemical Hygiene Plan

• To ensure that all individuals at risk are adequately informed about work in the laboratory, its risks, methods to protect themselves, and procedures to follow in the event of an emergency

• To become familiar with common concerns noted during laboratory inspections and with good chemical hygiene practices associated with laboratory work

OSHA LABORATORY STANDARD

• The OSHA “Occupational Exposures to Hazardous Chemicals in Laboratories” Standard, or Laboratory Standard for short, requires employers to protect laboratory workers from health hazards associated with chemical exposure in the laboratory (see OSHA Lab Standard at http://www.osha.gov/pls/oshaweb/owadisp.show_document?p_table=STANDARDS&p_id=10106

)

OSHA LABORATORY STANDARDOSHA DEFINITIONS

Laboratory - A workplace where relatively small quantities of hazardous chemicals are used on a non-production basis

Laboratory Scale – Containers used for reactions, transfers, and handling are small enough to be easily and safely manipulated by one person

Page 5: Tulane University - Office of Environmental Health & Safety (OEHS) OSHA LABORATORY STANDARD & CHEMICAL SAFETY FOR TULANE LABORATORY EMPLOYEES May 2012

OSHA LABORATORY STANDARDDOES IT APPLY TO YOUR LAB?

• The determination of whether the OSHA Laboratory Standard applies as opposed to the OSHA General Industry Standard depends on “laboratory use” and “laboratory scale” criteria.

• Some OSHA substance specific standards require coverage to remain under that standard rather than the Lab Standard. (Example: The use of formaldehyde in labs is covered under OSHA Formaldehyde Standard rather than the OSHA Lab Standard.)

• Most Tulane labs fall under the OSHA Lab Standard.

OSHA LABORATORY STANDARDEXEMPTIONS

• Quality control laboratories connected with production processes that perform repetitive tasks are exempt from the Lab Standard.

• Uses of hazardous chemicals which provide no potential for employee exposure, such as medical labs which only use prepackaged test kits, are exempt from the Lab Standard.

OSHA LABORATORY STANDARDEXPOSURE CONTROL – FUME HOODS

• Before using toxic or volatile chemicals in a fume hood, adequate hood performance needs to be confirmed.

• Hoods at Tulane are required to have an alarm or airflow indicator/monitor. At the very least, use a piece of tissue to make sure the hood is exhausting.

Page 24: Tulane University - Office of Environmental Health & Safety (OEHS) OSHA LABORATORY STANDARD & CHEMICAL SAFETY FOR TULANE LABORATORY EMPLOYEES May 2012

Tulane University - Office of Environmental Health & Safety (OEHS)

OSHA LABORATORY STANDARDEXPOSURE CONTROL – FUME HOODS

• Typically a working fume hood should exhaust at a rate of 80-120 feet per minute face velocity.

• Report problems promptly to Facilities Services.

• DO NOT perform work with toxic or volatile chemicals if the hood is not operating properly! This is the user’s responsibility.

OSHA LABORATORY STANDARDPRIOR APPROVAL

• Contact OEHS for prior approval and safety advice when using high risk substances (i.e., explosives, “select” carcinogens, reproductive toxins, substances with a high degree of acute toxicity), for grant “environmental compliance” statements, or for projects with possible safety concerns.

Page 42: Tulane University - Office of Environmental Health & Safety (OEHS) OSHA LABORATORY STANDARD & CHEMICAL SAFETY FOR TULANE LABORATORY EMPLOYEES May 2012

Tulane University - Office of Environmental Health & Safety (OEHS)

OSHA LABORATORY STANDARDPRIOR APPROVAL

• Whenever high risk substances such as explosives, “select” carcinogens, reproductive toxins, or substances having a high degree of acute toxicity are used, a protocol sheet describing the project and the safety procedures/precautions that will be followed should be submitted to OEHS for review.

Page 43: Tulane University - Office of Environmental Health & Safety (OEHS) OSHA LABORATORY STANDARD & CHEMICAL SAFETY FOR TULANE LABORATORY EMPLOYEES May 2012

Tulane University - Office of Environmental Health & Safety (OEHS)

OSHA LABORATORY STANDARDPRIOR APPROVAL• Many grants require an environmental

compliance statement be signed by the OEHS Director stating the researcher is in compliance with environmental health and safety laws.

• OEHS reviews these protocols in depth, determines if the researcher is in compliance, suggests additional safety precautions that may be needed, etc.

• DO NOT wait until a grant is due to submit such protocols. It takes time to do this review.

ORGANIC PEROXIDESOrganic peroxides tend to be shock or light sensitive:

• Know the hazards specific to the chemical (MSDS)• Order only what is needed in small container sizes• Date containers when received, when opened, and

when to discard; Store properly• Use correct PPE• Routinely test for peroxides• Know what to do in an emergency; clean up spills

immediately• Dispose of properly and in a timely manner

Page 93: Tulane University - Office of Environmental Health & Safety (OEHS) OSHA LABORATORY STANDARD & CHEMICAL SAFETY FOR TULANE LABORATORY EMPLOYEES May 2012

Tulane University - Office of Environmental Health & Safety (OEHS)

ORGANIC PEROXIDESOrganic peroxides tend to be shock or light sensitive:

• Be especially wary of diethyl ether which is highly flammable and volatile and which may start to form peroxides as soon as 6 months from opening. Date container when it is opened and try to use or dispose of material within 6 months of opening.

Tulane University - Office of Environmental Health & Safety (OEHS)

SCALE-UP OF EXPERIMENTSScaling up an experiment can lead to an explosion. Prepare for an

emergency:

• Scale-up is frequently a contributing cause for an energetic incident

• As the scale of a reaction increases, the need for more efficient heat removal is needed

• Heat which cannot safely dissipate to the surroundings may be retained in the reaction vessel leading to a rapid increase in temperature and reaction rate

• The end result is a violent reaction• Monitor temperature; provide cooling

Page 96: Tulane University - Office of Environmental Health & Safety (OEHS) OSHA LABORATORY STANDARD & CHEMICAL SAFETY FOR TULANE LABORATORY EMPLOYEES May 2012
