Your laboratory can be a safer
place if you follow safety procedures, use personal
protective equipment, fume hoods and other engineering controls.

Chapter 6. Pollution Prevention and Waste
Minimization
There are many ways that a
laboratory can reduce its emissions to the atmosphere,
prevent pollutants from entering the sewer and minimize its waste generation.
6.1 Pollution Prevention
6.2 Environmentally Sound Recycling
6.3 Minimize Waste
6.4 Reduce Environmental Risks
6.5 Manage Waste Efficiently
Chapter 7. Chemical Disposal Procedures
This chapter contains an alphabetical list of chemical disposal procedures. The
back
half of this part explains how to obtain on-site chemical waste disposal
services from
the Safety Department at no cost to you.
7.1 In-Lab Chemical Management
7.2 On-Site Hazardous Materials Management Service
Chapter 8. Laboratory
Animals and Animal Tissue Disposal
Chapter 9. Bloodborne Pathogens, Sharps and
Medical Waste
Bloodborne pathogens present an
hazard to many types of workers. The Bloodborne
Pathogens Program is designed to address and reduce the risk of injury. Because
workers are at risk daily, sharps (e.g., needles, syringes, razor blades) and
laboratory
glass disposal requires precautions to prevent injuries to you, custodians and
waste
handlers.
9.1 Bloodborne Pathogens Program
9.2 Safe Handling of Human Blood and OPIM in Laboratories
9.3 Sharps and Laboratory Glass Disposal
9.3 Medical and other Regulated Sharps / Glass Disposal
Annex 9-1. Human Blood and OPIM Spill Cleanup Procedures
Annex 9-2. Sharps and Laboratory Glass Disposal
Appendix A. Disposal Procedures by Chemical
This is an alphabetical list of
chemicals and their corresponding disposal procedures
found in Chapter 7. If you don't find a chemical on this list, use the On-site
Service
described in Section 7.2 of Chapter 7.
Appendix B. OSHA Laboratory
Standard
The
Occupational Health and Safety Administration (OSHA) rules require laboratories
to use chemicals safely and prevent hazardous exposures to laboratory personnel.
B.1 Keep Exposures Below Permissible Limits
B.2 Write a Chemical Hygiene Plan
B.3 Inform and Train Laboratory Personnel
B.4 Provide for Medical Consultation / Examinations
B.5 Keep Chemical Labels Intact
B.6 Maintain Material Safety Data Sheets
B.7 Take Precautions with Respirators
B.8 Keep Safety Records
Annex B-1. Occupational Exposures to Hazardous Chemicals in Laboratories
(29 CFR 1910.1450)
Appendix C. Chemical Hygiene Plan Template
The OSHA Laboratory Standard
law requires that each laboratory have a Chemical
Hygiene Plan. This appendix is a template that you can easily complete and
generate a
Chemical Hygiene Plan for you lab.
Annex C-1. Frequently Asked Questions about Chemical Hygiene Plans
Appendix D. Particularly Hazardous
Substances
The OSHA Laboratory Standard
law requires additional precautions for the use of
particularly hazardous substances, which are listed in this appendix.
D.1 Select Carcinogens
D.2 Reproductive Toxins
D.3 Substances with a High Degree of Acute Toxicity
D.4 Particularly Hazardous Substance Use Approval Form
Annex D-1. Select Carcinogens (with footnote)

Appendix E. Laboratory
Safety Survey
Appendix F. Preventing
Chemical Incompatibility Hazards
When
combined, incompatible chemicals can generate a toxic gas, start a fire, or
cause
an explosion. Careful chemical storage is also important to prevent
incompatibility
problems in a fire.
F.1 Containment to Prevent Hazards
F.2 Safe Chemical Storage
F.3 Preventing Binary Mixture Hazards
F.4 Safe Procedures for Chemical Work
F.5 Strong Oxidizer-Reducer incompatibilities

Appendix G. Training for Laboratory
Personnel
The OSHA Laboratory Standard law
requires that laboratory personnel be trained and
informed of chemical hazards. This appendix contains a training outline so that
you
can use this Guide to comply with OSHA’s training requirement.

Appendix H. EPA Hazardous
Waste Law
U.S. Environmental Protection Agency
(EPA) requires the safe disposal of chemical
hazardous waste. You will comply with the law by following the disposal
procedures
in Part G. This part further explains EPA’s law.
H.1 What is an EPA Hazardous Waste?
H.2 Storage of EPA Hazardous Waste
H.3 Waste versus Surplus Chemical
H.4 Prohibited Disposal Methods

Anecdotal Information
The old saying, "Experience is a hard
teacher, but some will have none other,"
suggests that learning from other's experience may be safer. Here are some
musings
from our chemist which may prove useful.
I.1 Things that go Bump in the Lab
I.2 Why Water Splatters on Sulfuric Acid (and Not When Sulfuric Acid is
Added to Water)
I.3 Peroxide Crystals found in isopropanol
I.4 Cyanogen Bromide
I.5 Nitrocellulose Decomposition Progression
Appendix J. Answers to
Review Questions
Here you can see what we thought were
the correct answers. In some instances
"correctness" is a judgment call. Remember the goal is protect the worker first.
