Appendix T4 Requirements
for the Safe Use of Chemicals |
||
|
|||
Jefferson Lab has determined that working with chemicals carries an unmitigated Risk Code >2. At a minimum all tasks requiring chemicals are discussed with the supervisor prior to commencement of work. An Operational Safety Procedure (OSP) is written for work considered to be Risk Code >2 in accordance with ES&H Manual Chapter 3210 Work Planning, Control, and Authorization Process. |

Purpose
Jefferson Lab recognizes that a chemical’s safety data sheet
(SDS) provides comprehensive safety requirements. Chemical workers are to review
the chemical’s SDS and this appendix, and follow the more stringent of the two requirements.
This program satisfies applicable federal, state, and local requirements as outlined in ES&H Manual Chapter 2410 Appendix T1 Hazard Issues List.
2.0
Scope
It is recognized that listing the
requirements for every chemical used at Jefferson Lab would be prohibitive, it
is therefore required that qualified chemical workers read and follow the requirements/recommendation listed on a chemical’s SDS.
This procedure defines actions required by Jefferson Lab in addition to or
above those listed on the SDS.
This appendix’s process steps are performed in coordination with ES&H Manual Chapter 6610 Chemical Hygiene Program.

Responsibilities
NOTE: Management authority may be delegated at the discretion of the responsible manager.
3.1
Qualified
Chemical Worker
· Review and abide by the requirements/recommendations on a chemical’s SDS.
· Ensure the safety of yourself and others during operations. Contact your supervisor/Subcontracting Officer’s Technical Representative/Sponsor if events progress beyond your training.
· Be knowledgeable regarding the location and use of emergency showers, eyewash units, spill kits, and appropriate fire extinguisher(s).
3.2
Supervisor/Subcontracting
Officer’s Technical Representative (SOTR)/Sponsor
· Authorize access to areas where chemicals are used and/or stored only to qualified and appropriately trained workers.
·
Establish decontamination procedures which include the periodic wiping
down of work surfaces to remove drips, residue, and spills.
·
Ensure emergency
showers, eyewash units, spill kits, and appropriate fire
extinguisher(s) are available and in proper working order.
4.0
Expectations
Unless otherwise stated, anyone at Jefferson Lab may perform the process steps outlined below.
·
Contact the Industrial
Hygienist
to review chemical procedures to ensure special handling requirements are
in-place.
·
Post warning signs and contact information outside areas when
unattended chemicals are “in-process,” in accordance with an approved work control document
(e.g., an Operational
Safety Procedure (OSP) form).
·
Wear appropriate personal protective equipment.
See ES&H Manual Chapter 6610 Appendix T5 Personal Protective Equipment
for Chemical Handling.
·
Keep lids of chemical containers closed
except when adding or removing contents.
·
Open containers slowly and carefully.
·
When soaking components in chemicals outside
of a fume hood, place a lid over the container. Refer to ES&H Manual Chapter 6630
Appendix T1 Engineering Controls –
Local and Portable Exhaust Systems for
information on the proper
use of chemical
fume hoods.
· When mixing two substances, slowly add the higher density substance to the lower, and stir continuously.
· Never empty carboys or drums of chemicals by means of air pressure.
· Use a mechanical aid or a pipette bulb for pipetting.
·
Contact the Fire
Protection Engineer to ensure adequate fire safety and control precautions
have been taken for the work area.
·
Control all ignition sources when handling
flammable chemicals.
·
Use
grounding and bonding techniques to prevent static build-up particularly while
performing transfer operations between containers. Contact the Industrial
Hygienist if
you need assistance with this operation.
