Reasons for PPE
Personal Protective Equipment (PPE)
“Protective equipment, including personal
protective equipment for eyes, face, head, and
extremities, protective clothing, respiratory
devices, and protective shields and barriers, shall
be provided, used, and maintained in a sanitary
and reliable condition wherever it is necessary by
reason of hazards of processes or environment,
chemical hazards, radiological hazards, or
mechanical irritants encountered in a manner
capable of causing injury or impairment in the
function of any part of the body through
absorption, inhalation or physical contact.”

PPE
EYE PROTECTION
“The employer shall ensure that each affected
employee uses appropriate eye or face
protection when exposed to eye or face
hazards from flying particles, molten metal,
liquid chemicals, acids or caustic liquids,
chemical gases or vapors, or potentially
injurious light radiation.”
http://www.osha.gov/pls/oshaweb/owadisp.show_document?p_table=STANDARDS&p_id=9778
EYE PROTECTION
Chemical Handling – Splash Hazard
• Splash Goggles, eyecup and cover types.
• For severe exposure, use face shield. See
notes (3), (11).”
(3) Face-shields should only be worn over primary eye protection (spectacles or goggles).
(11) Ventilation should be adequate, but well protected from splash entry. Eye and face protection
should be designed and used so that it provides both adequate ventilation and protects the wearer
from splash entry.

Protective Eyewear
GLOVES
Selection guidelines for hand protection.
Gloves are often relied upon to prevent cuts,
abrasions, burns, and skin contact with chemicals
that are capable of causing local or systemic effects
following dermal exposure. OSHA is unaware of any
gloves that provide protection against all potential
hand hazards, and commonly available glove
materials provide only limited protection against
many chemicals. Therefore, it is important to select
the most appropriate glove for a particular
application and to determine how long it can be
worn, and whether it can be reused.

GLOVES
With respect to selection of gloves for
protection against chemical hazards:
(A) The toxic properties of the chemical(s) must be determined; in
particular, the ability of the chemical to cause local effects on the skin
and/or to pass through the skin and cause systemic effects;
(B) Generally, any "chemical resistant" glove can be used for dry powders;
(C) For mixtures and formulated products (unless specific test data are
available), a glove should be selected on the basis of the chemical
component with the shortest breakthrough time, since it is possible for
solvents to carry active ingredients through polymeric materials
(D) Employees must be able to remove the gloves in such a manner as to
prevent skin contamination.

REACT-OX® Chemical Resistant Gloves
Nitrile type or similar
Other compatible with Sulfuric
Acid and Sodium Hydroxide
MINIMUM PPE
• A work uniform affording minimal protection,
used for nuisance contamination only.
• Chemical resistant gloves.
• Boots/shoes, chemical-resistant steel toe and
shank.
• Safety glasses or chemical splash goggles.
• Hard hat.
WHEN TO USE MINIMUM PPE
• Pump draw downs.
• Water Board maintenance/ repair.
• Probe calibration.
RECOMMENDED PPE
• Chemical-resistant clothing (i.e.: overalls and
long-sleeved jacket; coveralls; one or two-piece
chemical-splash suit; disposable chemicalresistant overalls).
• Chemical-resistant Gloves.
• Boots, outer chemical-resistant, steel toe and
shank or boot-covers, outer chemical-resistant
(disposable) over standard PPE boots.
• Hard hat.
• Tight fitting safety glasses with side shields or
chemical splash goggles.
• Face shield.
WHEN TO USE RECOMMENDED PPE
• Repairing Leaks and pumps (if line, fittings
and/or pump is unhooked from chemical
source and flushed with water-minimum PPE
can be used).
• Tote exchange.
• Chemical clean up.
Tychem® Protective Suit (Acid Resistant)
TOTE RECEIVING AND EXCHANGE SOP
1. Review Tote Condition
• Check valve for visible damage obtained during
shipping. Do not use if damaged
2. Move tote from storage area to chemical
room
3. Don Chemical PPE appropriate to Material
being handled.
TOTE RECEIVING AND EXCHANGE SOP
4. With PPE on, remove the cover cap and any
plastic or foil seal on the bottom valve.
5. Use Lock-out Tag-out. Turn off and unplug
chemical pump or pumps.
6. Shut off bottom valve on old tote and any
valve on the chemical line at the tote.
TOTE RECEIVING AND EXCHANGE SOP
7. Remove cam lock fitting and drain any chemical
found in cam lock fitting into a plastic catch
bucket. Set tote fitting and chemical line in
bucket and in a secure out of the way location.
8. Replace cap on the bottom valve of the old tote.
9. Remove old tote from chemical room.
10. Move new tote into position in the chemical
room.
TOTE RECEIVING AND EXCHANGE SOP
11. If female CAM was leaking, replace seal now.
12. Lock chemical female cam lock fitting onto
male tote fitting.
13. With PPE still on, open tote valve and check
for leaks. Open any other chemical supply
valves between tote and chemical tote.
TOTE RECEIVING AND EXCHANGE SOP
14. Turn on pump(s) and bleed the chemical
lines of air at chemical pump or before
Griffco back pressure valve.
15. Wash down tote area and chemical lines.
16. Wash Down, remove and store acid suit, face
shield, etc.
CHEMICAL FEED LINE REPAIR SOP
1. Don appropriate PPE
2. On entering chemical room review all lines
for leaks.
3. Use Lock-out/ Tag-out. Turn off power and
unplug the chemical pump to be repaired or
to pump supplying line to be repaired. If leak
is a spray, pump can be turned off through
the WebMaster.
CHEMICAL FEED LINE REPAIR SOP
4. Turn off or close valve on bottom of tote and
any other valves in the line supplying the
pump or line to be repaired.
5. Wash down area of leak.
6. Locate repair supplies
7. Repair or replace chemical tubing, tubing

pump into “Hand” or plug pump into a
powered outlet.
10. Bleed air out of chemical feed lines at
chemical pump or before Griffco back pressure
