OCCUPATIONAL EXPOSURE TO HAZARDOUS
CHEMICALS IN LABORATORIES
29 CFR 1910.1450
On January 31, 1990, the Occupational Safety and Health Administration (OSHA) published in
the Federal Register the Occupational Exposure to Hazardous Chemicals in Laboratories
standard (Laboratory Standard), 29 CFR 1910.1450. The basis for this standard is a
determination by the Assistant Secretary that laboratories typically differ from industrial
operations in their use and handling of hazardous chemicals and that a different approach than
that found in OSHA's substance specific health standards is warranted to protect laboratory
workers.
The effective dates of the standard are:
This standard becomes effective 05/01/90
Implementation of a Chemical Hygiene Plan 01/31/91
The purpose of the standard is to ensure the hazards of all chemicals handled and used in
laboratories are evaluated, and the information concerning the hazards is transmitted to affected
employers and employees by means of a comprehensive Chemical Hygiene Plan.
Implementation of the OSHA Laboratory Standard requires extensive planning by companies
with laboratories affected by the standard. Responsibilities must be assigned and tasks defined
to assure effective implementation.
OSHA's Laboratory Standard is only one of many occupational safety and health items needing
managements' attention. This standard, like all OSHA standards and numerous safety and
health requirements, must be effectively managed by all levels of management. The
commitment and involvement of laboratory supervisors is very important for assuring proper
compliance with this standard.
This implementation manual contains an implementation plan, implementation schedule, the
complete OSHA Laboratory Standard, and a written Chemical Hygiene Plan for adaptation to
your facility. The Chemical Hygiene Plan is contained on an ASCI file diskette in the pocket
on the front cover for use in adapting the Chemical Hygiene Plan to the specifics at your
facility.
HOW TO USE THIS MANUAL
This manual is divided into four sections: the Implementation Plan, Part 1; the Implementation
Schedule, Part 2; the OSHA Laboratory Standard, Part 3; and, a Chemical Hygiene Plan, Part
4.
Part 1, the Implementation Plan, has eight sections each describing pertinent steps to take for
compliance with the OSHA standard. In addition, information is presented and explained in
detail to assist you with implementation. A message, printed in italics, is found at the end of
each section describing the applicable items of Part 2, the Implementation Schedule.
Part 2, the Implementation Schedule, should be completed by assigning responsible persons
and target completion dates. This schedule should be referred to on a continuing basis until all
items have been successfully implemented.
Part 3 contains a copy of the OSHA Laboratory Standard, 29 CFR 1910.1450. This section is
presented for your information and future reference.
Part 4 contains a Chemical Hygiene Plan which can be edited to your specific laboratory needs.
This section provides a good base for writing your Chemical Hygiene Plan.

OCCUPATIONAL EXPOSURE TO HAZARDOUS
CHEMICALS IN LABORATORIES
29 CFR 1910.1450
1. 0 APPLICABILITY
The Laboratory Standard applies to all employers engaged in the laboratory use of hazardous
chemicals. Laboratory use of hazardous chemicals is defined as the use or handling of
chemicals in which all of the following conditions are met:
(a) Chemical manipulations are carried out on a "laboratory scale". Laboratory
scale is defined as work with substances in which the containers used for
reactions, transfers, and other handling of substances are designed to be easily
and safety manipulated by one person. This definition excludes those
workplaces whose function is to produce commercial quantities of materials;
(b) Multiple chemical procedures or chemicals are used;
(c) The procedures involved are not part of a production process, nor in any way
simulate a production process; and
(d) "Protective laboratory practices and equipment" are available and in common
use to minimize the potential for employee exposure to hazardous chemicals.
This standard does not apply to:
(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 standard in
29 CPR part 1910, subpart Z, even if such use occurs in a laboratory.
(b) Laboratory uses of hazardous chemicals which provide no potential for
employee exposure.
Part I
Implementation Plan
Page 1 of 8
Where the standard does apply, it shall supersede, for laboratories, the requirements of all
other OSHA health standards in 20 CFR part 1910, subpart Z, except as follows:
(a) For any OSHA health standard, only the requirement to limit employee
exposure to the specific permissible exposure limit shall apply for laboratories,
unless that particular standard states otherwise or unless the action level (or in
the absence of an action level, the PEL) is routinely exceeded.
(b) Prohibition of eye and skin contact where specified by any OSHA health
standard shall be observed.
(c) Where the action level (or in the absence of an action level, the PEL) is routinely
exceeded for an OSHA regulated substance with exposure monitoring and
medical surveillance requirements, the employee exposure monitoring and
medical monitoring requirements of this standard shall apply.
Any substance specific standard can require coverage to remain under that standard rather than
under the laboratory standard. In the absence of a statement of preemption in a substance
specific standard, the determination of whether the laboratory standard applies must be
dependent on both "laboratory use" and "laboratory scale" criteria. Where these criteria are
met, the laboratory standard applies.
Upon completing the applicability criteria for the standard, complete Item Number 1 on the
Implementation Schedule contained in Part II of this manual.
2.0 ASSIGNMENTS
The Chief Executive Officer (CEO) has the ultimate responsibility for chemical hygiene
throughout the laboratory, and with assistance of other program administrators, must provide
continued support for chemical hygiene.
The CEO should assign a Chemical Hygiene Officer (GIO) to provide technical guidance in
the development and implementation of appropriate chemical hygiene policies and practices
2. 1 Chemical Hygiene Officer
The Chemical Hygiene Officer (CHO) is an employee who is qualified by training or
experience, to provide technical guidance for the continuing implementation of the
Chemical Hygiene Plan. The CHO should be designated by the employer.
Part I
Implementation Plan
Page 2 of 8
The duties of the CHO are outlined in Section 7.2 of the Chemical Hygiene Plan
contained in Part IV of this manual. The designation of the CHO should not be limited
by position description or job title within the organizational structure. The designation
should be based upon the individuals ability to fulfill the responsibilities of chemical
hygiene in the facility. The CHO reports directly to management in this capacity.
2. 2 Chemical Hygiene Committee
In large facilities, or facilities with multiple laboratories, the implementation of
compliance with this standard may best be accomplished by establishing a Chemical
Hygiene Committee.
If a Chemical Hygiene Committee is selected, it should be arranged so that all
laboratory workers have maximum access to the committee members.
The Chemical Hygiene Committee should meet on a regular basis. Minutes of these
meetings should be presented to management.
Upon completing the assignments of personnel discussed in this section, complete Item
Number 2 on the Implementation Schedule contained in Part II of this manual.
3.0 CHEMICAL HYGIENE PLAN
Paragraph (e) of the standard requires employers covered by the standard to develop and carry
out the provisions of a written Chemical Hygiene Plan (CHP).
The CHP is a written program outlining procedures, equipment, personal protective
equipment, and work practices capable of:
(a) protecting employees from the health hazards presented by exposure to
hazardous chemicals in the laboratory; and
(b) maintaining employee exposures below the OSHA Permissible Exposure
Limits.
The CHO should be responsible for the development and implementation of the CHP. The
CHP should be readily available to employees, employee representatives, and upon request to
the Assistant Secretary of Labor.
