Before chemicals are ordered, the following questions should be considered:

What is the minimum

quantity needed

to complete the experiment?

Chemical Procurement

What is the least hazardous

chemical available that can

be used?

Is the chemical alreadyavailable? Check yourlaboratory 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


7/267

Chemical StorageChemical containers must be labeled with a minimum

of chemical name, hazard warnings.

Containers shall be dated when received and opened.Accompanying material safety data sheets must be kept.


8/268

Chemical Storage

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:

Use secondary containers or trays for corrosives

and toxic solvents.


9/269

When refrigerating flammables, only use refrigeratorsspecifically designed for flammable materials.

Do not store food in chemical storage refrigerators.

Label chemical storage refrigerators with the following:

No Food Chemical Storage Only

Chemical StorageGeneral Considerations:


10/2610

At a minimum, chemicals should be segregated as:

Chemical Storage Hazard Class

Corrosives

Flammable Liquids

Oxidizers

Poisons or Toxic Chemicals

Reactive (water or time sensitive)


11/2611

Store concentrated acids and bases separately.

Keep corrosives away from organic chemicals andcombustible materials.

Use secondary catch basins for concentrated acidsand bases.

Chemical Storage Corrosives

OH-H+


12/2612

Chemical Storage

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 arefrigerator it must be in an explosion-proof (lab-

safe) refrigerator.

13

Store oxidizers away from flammable and combustiblematerials.

Store oxidizers away from reducing agents.

Maintain the minimum quantity needed and dispose ofunneeded material immediately.

Chemical Storage xidizers


14/26

14

Store highly toxic materials in a dedicated storage fumehood.

Maintain the minimum quantity needed and dispose of

unneeded material immediately.

Store in unbreakable containers or use secondarycontainers.

Label storage areas with designated area signs.

Chemical StorageTo ic Chemicals


15/26

15

Use the MSDS and labels for storage information.

Bring only quantities needed for immediate use into the

laboratory.

Store water reactive chemicals away from all sources of

water or in water tight containers.

Store thermally unstable chemicals in approvedrefrigerators.

Chemical Storage Reactive

Chemical Transporting


17/26

17

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.

Transporting Chemicals


18/26

18

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.

Transporting Chemicals

Chemical Manipulation


20/26

20

Be familiar with chemical properties and products of chemicalreactions.

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.



21/26

21

Use chemical fume hoods to control exposure as chemicalsare transferred.

Use chemical fume hoods to control exposure duringthe experiment.

Wear the appropriate personal protective equipment

(chemical splash goggles, gloves, etc.).

Have disposal containers ready ahead of time.

Chemical Safety : An Incident

Report 2008 , UCLA , Chemistry Laboratory , Run byProfessor Harran.

23 Year old Lab worker Sheri Shangji

severely burned in a Chemical Fire

50 % Burns , With severe 3rddegree burns to

the neck

Passed Away 18 Days Later.

The Investigation : Cal/OSHA


25/26

The Outcome

A Brilliant Young Researcher in Sheri Sangji

was lost at a early age

Criminal charges pressed against the

University and the Professor ( Three felony

counts for violating public safety)

Conviction could result in almost 4.5 years of

Prison time with 1 Million$ in Fines
