HSR Safety & Health Resource Guide
Introduction
Purpose
The purpose of this Health and Safety (HSR-5)
Safety Guide is to provide a single-source
document for addressing your safety questions.
The guide is not intended to be a compliance
document, but rather a resource document. The
guide does not set policy and therefore, does not
contain policies pertaining to human resources,
safety or emergency procedures.
In some cases, HSR-5 policies may be restated or
summarized, but all who use this guide must read
the referenced controlled document or source
document for additional details
Scope
Responsibilities for safety are outlined in the
individual documents referenced within the text
of each section of this guide. References include:
Laboratory Implementation Requirements
(LIRs) and Guidance (LIG) documents
Occupational Safety and Health Administration
(OSHA) standards
National Fire Protection Administration (NFPA)
guidance
National Electrical Code (NEC) guidance
American National Standards Institute (ANSI)
recommendations
Additionally, where applicable, Laboratory
training requirements are listed.

Confined Space
Introduction
A confined space is any space that meets the following
criteria:
is large enough and is configured so that a
person can bodily enter and perform assigned work,
has limited access or exit, and
is not designed for continuous occupancy.
If all three criteria are not present, the space is not a
confined space.
Requirements
After a space is identified as a confined space, it must be
classified as either a nonpermit or permit-required confined
space. See Table 2.
Table 2. Confined Space Definitions
Definition
A confined space that does not contain or
have the reasonable potential to contain
any hazard capable of preventing self-
rescue or causing death or serious physical
harm.
NOTE:
If a new hazard is introduced
during the course of work, a nonpermit-
confined space can become a permit-
required confined space.
A confined space has the following
inherent or introduced primary hazard
characteristics:
contains or has the potential to contain a
hazardous atmosphere;
contains a material that has the potential
to engulf the entrant;
has an internal configuration that could
entrap or asphyxiate an entrant; or
contains any other recognized serious
safety or health hazard.

Entry Requirements
Any time a confined space is entered, an authorized worker
must obtain the confined space evaluation report for the
space to be entered and ensure that the evaluation is
accurate. The HSR-5 and other Health and Safety
Professionals are authorized to evaluate confined spaces.
All authorized employees must receive the required
training. See Table 3.
Table 3. Confined Space Requirements
Requirements
A copy of the confined space evaluation
must be available at the point of entry and
the atmosphere should be monitored before
anyone enters the space.HSR-5 and other
Health and Safety professionals can
conduct air monitoring.
A permit must be completed by an
authorized worker and signed by the
entry supervisor.
The atmosphere must be monitored
before entry and throughout the entry.
An attendant must be posted outside the
space and maintain communications with
the entrant. The attendant must also have
a means to communicate with emergency
services.
Nonentry rescue equipment must be used
unless it increases the overall risk of
entry.
If an onsite rescue team is not available
LAFD must be notified.

Cranes, Hoists, Lifting Devices, and
Rigging
Introduction
Using cranes, hoists, lifting devices, and rigging can be
hazardous. If this equipment is improperly used or
maintained, property and equipment can be damaged and
personnel can be seriously injured. The hazards associated
with the use of lifting devices can be minimized through
operator training and certification, routine inspections, and
proper maintenance.
Requirements
Only trained and qualified personnel who have received a
formal, documented review of proficiency training are
permitted to operate general-purpose installed lifting
devices (GPILDs). The GPILDs are defined as cranes and
hoists that were installed as part of the original building
construction, or commercially available cranes and hoists
that are permanently attached to the building or other
structure.
The GPILDs must be load-tested and certified.
The GPILDS must have a current annual inspection as
identified by a dated gray tag (Form 1594) posted on the
lifting device. Evidence of mechanical and electrical
preventative maintenance may also be posted; however,
