HEMICAL P ROCUREMENT 5 Before chemicals are ordered, the following
questions should be considered: Before chemicals are ordered, the
following questions should be considered: What is the minimum
quantity needed to complete the experiment? What is the least
hazardous chemical available that can be used? Is the chemical
already available? Check your laboratory chemical inventory. How
should the chemical be stored? Is the laboratory equipped to handle
a spill? Are personnel trained on how to safely handle the
chemical? CHEMICAL STORAGE AREA Slide 7 6 Chemical Storage Slide 8
C HEMICAL S TORAGE This section will first discuss general
considerations and requirements for chemical storage. Next, it will
provide specific information for the storage of chemicals by hazard
class. 7 Slide 9 C HEMICAL S TORAGE - R EQUIREMENTS There must be
an inventory list of hazardous chemicals. There must be an
inventory list of hazardous chemicals. Chemical containers must be
labeled with a minimum of chemical name, hazard warnings and target
organs. Chemical containers must be labeled with a minimum of
chemical name, hazard warnings and target organs. Containers shall
be dated when received and opened. Containers shall be dated when
received and opened. Accompanying material safety data sheets must
be kept. 8 Slide 10 C HEMICAL S TORAGE 9 Plan ahead for spills,
accidents or emergencies. Be aware of special storage conditions
such as temperature, relative humidity or limited shelf life.
Segregate chemicals by hazard class or compatibility. General
Considerations: Slide 11 C HEMICAL S TORAGE If available, use
ventilated cabinets for volatile toxics and odoriferous chemicals.
Use approved flammable storage cabinets for flammable liquids. Use
secondary containers or trays for corrosives and toxic solvents. 10
General Considerations: Slide 12 C HEMICAL S TORAGE When
refrigerating flammables, only use refrigerators specifically
designed for flammable materials. Do not store food in chemical
storage refrigerators. Label chemical storage refrigerators with
the following: No Food Chemical Storage Only 11 General
Considerations: Slide 13 C HEMICAL S TORAGE Avoid storing liquid
chemicals above eye level. Avoid storing chemicals in aisle ways.
Avoid over stocking shelves. Avoid storing heavy containers above
shoulder level. Avoid storing chemicals in fume hoods or on counter
tops. Avoid storing chemicals near sources of heat or in direct
sunshine. 12 General Considerations: Slide 14 C HEMICAL S TORAGE H
AZARD C LASS At a minimum, chemicals should be segregated as: At a
minimum, chemicals should be segregated as: 13 Corrosives Flammable
Liquids Oxidizers Poisons or Toxic Chemicals Reactive (water or
time sensitive) Slide 15 C HEMICAL S TORAGE C ORRSIVES C HEMICAL S
TORAGE C ORROSIVES Store concentrated acids and bases separately.
Keep corrosives away from organic chemicals and combustible
materials. Use secondary catch basins for concentrated acids and
bases. 14 OH - H+H+H+H+ Slide 16 C HEMICAL S TORAGE Store in
approved safety cans or cabinets Segregate from oxidizing acids and
oxidizers. Keep away from any source of ignition: flames, heat or
sparks. Know where fire fighting equipment is stored and how to
use. If volatile flammable liquids are stored in a refrigerator it
must be in an explosion-proof (lab-safe) refrigerator. 15 Slide 17
C HEMICAL S TORAGE As a general rule of thumb, no more than 10
gallons of flammable liquids should be stored outside of an
approved flammable storage cabinet. Hospital patient areas are
typically much less (1 to 2 gallons). 16 Slide 18 C HEMICAL S
TORAGE XIDIZERS Store oxidizers away from flammable and combustible
materials. Store oxidizers away from reducing agents. Maintain the
minimum quantity needed and dispose of unneeded material
immediately. 17 Slide 19 C HEMICAL S TORAGE T O IC C HEMICALS Store
highly toxic materials in a dedicated storage fume hood. Maintain
the minimum quantity needed and dispose of unneeded material
immediately. Maintain the minimum quantity needed and dispose of
unneeded material immediately. Store in unbreakable containers or
use secondary containers. Store in unbreakable containers or use
secondary containers. Label storage areas with designated area
signs. Label storage areas with designated area signs. 18 Slide 20
C HEMICAL S TORAGE R EACTIVE Examples of reactive chemicals would
include, but not be limited to: 19 Water reactive chemicals.
Pyrophors, which react with air. Peroxide forming chemicals, which
form shock sensitive explosives. ETHER Slide 21 C HEMICAL S TORAGE
R EACTIVE Consult the MSDS and labels for storage information.
Bring only quantities needed for immediate use into the laboratory.
Date all reactive chemicals as soon as they are received. Do not
open material after the expiration date. 20 Slide 22 C HEMICAL S
TORAGE R EACTIVE Store pyrophoric chemicals away from flammables.
Store perchloric acid away from reducing agents. Store perchloric
acid bottles in glass or ceramic trays. Store peroxidizable
materials away from heat and light. 21 Slide 23 C HEMICAL S TORAGE
R EACTIVE Store water reactive chemicals away from all sources of
water or in water tight containers. Store thermally unstable
chemicals in approved refrigerators. Consider explosion relief
boxes for highly sensitive materials. Restrict access to the
storage area. 22 Slide 24 23 Chemical Transporting Slide 25 T
RANSPORTING C HEMICALS If chemicals are transferred to a second
container, make sure the new container is labeled with the chemical
name. Use secondary containers, with handles, made of rubber,
plastic or metal. Secondary containers should be large enough to
contain all of the chemical contents. 24 Slide 26 T RANSPORTING C
HEMICALS Make sure the pathway is clear of obstructions and
tripping hazards. Plan ahead for spills. Transport only the
quantity needed to complete the experiment. Use sturdy carts when
transporting heavy containers or transporting over long distances.
25 Slide 27 26 Chemical Manipulation Slide 28 C HEMICAL M
ANIPULATION Be familiar with chemical properties and products of
chemical reactions. Be prepared for chemical spills and clean up
spills immediately. Plan ahead have apparatus and associated
equipment ready before chemicals are used. Use the appropriate
equipment, such as funnels, beakers and spatulas when transferring
chemicals. 27 Slide 29 C HEMICAL M ANIPULATION Use chemical fume
hoods to control exposure as chemicals are transferred. Use
chemical fume hoods to control exposure during the experiment. Wear
the appropriate personal protective equipment (chemical splash
goggles, gloves, etc.). Have disposal containers ready ahead of
time. 28 Slide 30 29 The End Questions ? Slide 31 30 Before
