Engineering Controls


NOTE
: Specific information on engineering controls is to be added to the
Protocol/Procedure section.


Work with
metallic

hydroxide
s

should be conducted in a fume hood unless other
controls are designated in the Protocol/Procedure section. Sash height should be kept
low to avoid escaping fumes and provide a physical barrier



Personal Protective Equipment (PPE)


NOTE:

Specific information on PPE selection is to be added to the Protocol/Procedure
section.


Respiratory protection

NOTE
: Lab personnel intending to use/wear a respirator mask must be trained and fit
-
tested by EH&S. This is a regulatory requirement.


Respirat
ors should be used only under any of the following circumstances:



As a last line of defense (i.e., after engineering and administrative controls have
been exhausted).



When Permissible Exposure Limit (PEL) has exceeded or when there is a
possibility that PE
L will be exceeded.



Regulations require the use of a respirator.



An employer requires the use of a respirator.



There is potential for harmful exposure due to an atmospheric contaminant (in
the absence of PEL)



As PPE in the event of a chemical spill clean

up process


Hand Protection

Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal
technique (without touching glove's outer surface) to avoid skin contact with this
product. Dispose of contaminated gloves after use in
accordance with applicable laws
and good laboratory practices. Wash and dry hands.


NOTE:

Lab
-
specific and chemical
-
specific information on glove selection may be
included in the Protocol/Procedure section. Refer to glove selection from the link below:

Eye Protection

Safety glasses with side shields

or tightly fitting safety goggles

are required
. Use face
shield (8
-
inch minimum) when appropriate. Use equipment for eye protection tested and
approved under appropriate government standards such as NIOSH (US) or EN 166(EU)
or ANSI Z87.1.


Skin and Body
Protection

Long pants, closed
-
toed and closed
-
heeled shoes, cotton
-
based clothing/attire, and lab
coat
/apron

must be worn for protecting against chemical hazards.


Hygiene Measures

Handle in accordance with good industrial hygiene and safety practice. Wash

hands
before breaks and at the end of workday.



First Aid Procedures

Notify supervisor and EH&S immediately.

Follow up with a call to 510
-
642
-
9090 to
report the incident.



If inhaled

Move person into fresh air. If not breathing, give artificial respiration.
Immediately
c
onsult a physician.


In case of skin contact

Take off contaminated clothing immediately. Wash off with soap and plenty of water for
15 minutes. Take victim immediately

to hospital. Consult a physician.


In case of eye contact

Rinse thoroughly with plenty of water
using an emergency eyewash station
for at least
15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid
immediately.


If swallowed

Do
not induce vomiting

unless directed otherwise by the SDS
. Never give anything by
mouth to an unconscious person. Rinse mouth with water. Consult a physician.

Special Handling and Storage Requirements


NOTE:

Specific information on handling and storage is to be added to the
Protocol/Procedure section.


Working alone

Certain extremely hazardous operations should not be performed if the PI or Lab Safety
Contact(s) are not present. Never work alone with extreme
ly hazardous
materials/operations. See the Protocol/Procedure section below for specific prohibitions
(if any) on working alone.


Precautions for safe handling

Wash thoroughly after handling. Use with adequate ventilation. Do not allow water to
get into t
he container because of violent exothermic reaction. Do not get in eyes, on
skin, or on clothing. Do not ingest or inhale. Avoid formation of dust and aerosols.
Provide appropriate exhaust ventilation at places where dust is formed.



Conditions for safe
storage


Store in a tightly closed container. Store in a cool, dry, well
-
ventilated area away from
incompatible substances. Keep away from strong acids. Keep away from water. Keep
away from metals. Keep away from flammable liquids. Keep away from organic
h
alogens. Absorb CO
2

and water
from the air.



Spill and Accident Procedure

-

Chemical Spill
Dial

911



Spill


Assess the extent of danger. Help contaminated or injured persons. Evacuate
the spill area. Avoid breathing vapors. If possible, confine the

spill to a small area
using a spill kit or absorbent material. Keep others from entering contaminated area
(e.g., use caution tape, barriers, etc.).




Small (<1 L)


If you have training, you may assist in the clean
-
up effort. Use
appropriate personal p
rotective equipment and clean
-
up material for chemical spilled.
Double bag spill waste in clear plastic bags, label and take to the next chemical waste
pick
-
up.



Large (>1 L)


Dial
911

and 510
-
642
-
9090 for assistance.



Chemical Spill on Body or Clothes


Remove clothing and rinse body thoroughly in
emergency shower for at least 15 minutes. Seek medical attention.
Notify supervisor
and EH&S immediately. Follow up with a call to 510
-
642
-
9090 to report the incident.



Chem
ical Splash Into Eyes


Immediately rinse eyeball and inner surface of eyelid
with water from the emergency eyewash station for 15 minutes by forcibly holding the
eye open. Seek medical attention.
Notify supervisor and EH&S immediately. Follow up
with a c
all to 510
-
642
-
9090 to report the incident.
