Laboratory Safety


Lab Safety Requirements - AWARENESS

• Know the safety rules and SOPs that apply to the work being done

• Know where to find and how to use laboratory safety equipment

• Know location of SDS for all chemicals used• Know what personal protective equipment is

available and use the right PPE for each job• Be alert to unsafe conditions and how to correct

them.


Hygiene• Wear eye protection at all times• Use protective equipment as needed – gloves available• No food or drink in the lab, storage rooms or lab fridge.• Never use lab glassware or equipment for food or drinks• No smoking• Handle chemical waste properly – find out where it goes• Avoid exposure to vapors, gases and aerosols – use snorkel• Use fume hood when necessary – Draeger testing• Wash hands after handling chemicals


Standard Operating Procedures (SOP)• SOPs should be developed and used for each

laboratory analytical method and routine laboratory task.

• An SOP manual, specific to the plant lab, should be available in the plant laboratory.

• The SOP manual should be updated whenever laboratory methods change or new methods are added.


Housekeeping• Clean work areas – After each test

• Spilled chemicals– Clean up immediately– Dispose of properly

• Ask questions!


Glassware• Prevent damage to

glassware– Careful handling– Storage procedures

• Glass tubing or flask sidearm - MicroDist– Exercise extreme care

inserting into rubber gaskets or stoppers

• Damaged glassware– Discard in sharps

container– Discard if cracked or

chipped


Sharps

• Approved sharps container – Must be available for

disposal of all sharps– Prevent accidental

exposure

• Sharps generally include– All damaged glassware– All needles


Flammability Hazards

Before lighting a flame, remove all flammable substances from the immediate area

Notify all occupants of laboratory in advance of using an open flame

Use an open flame only when necessary

Do not use an open flame or ovens to heat a flammable liquid

Store flammable materials properly

Fume Hoods

When transferring hazardous laboratory chemicals from one container to another

When using equipment during an operation which may produce splashing, sprays, fires, or a minor explosion

During operations which require heating or evaporating a solvent

When making acid or caustic solutions

During procedures that produce toxic, offensive, or flammable vapor

If a fume hood is not available in the laboratory, these types of laboratory procedures and chemical operations will not be conducted in the laboratory

Fume Hoods will be used:


Fume Hood – Frequency & Type of Monitoring

• Quarterly– Each fume hood

o Measure velocity of the air flowo At the face of the hoodo Using an anemometer or a

velometer


Storage of Chemicals

Chemicals stored with compatible chemicals

The amount of chemicals held in inventory shall be the minimum amount necessary to maintain consistent operation of the lab and plant chemical systems.

Maintain all chemical markings, placards, and labels, so that proper use and security is maintained. Store with labels outward facing.

Storage


• All liquids ( except pH buffers and metal standards)– Stored in liquid chemical storage area– Stored in approved chemical storage

cabinet • Acids and bases

– Separated on different shelves or in different cabinets

• Organics (alcohols, ketones, etc.)– Separated from acids and bases– Stored in a flammable cabinet

• All dry chemicals – Stored in dry chemical storage area

• Concentrated chemicals – Returned to proper storage area when

not in use • Prepared working reagents

– When properly labeled may be left on counters

Storage of Chemicals


Chemical Disposal• All chemicals will be disposed of in an environmentally

responsible manner– All laboratory chemicals that have become outdated, or

are no longer used, will be stored in a secured area and properly disposed of according to environmental procedures

– All used samples, prepared working reagents will be disposed of per the lab’s SOP

– Final disposal will be by environmental policy


Personal Protective Equipment and Laboratory Safety Equipment


Eye Protection

• Safety glasses with side shields must worn in lab• Goggles or face shields will be worn when there is

danger of splashing chemicals or flying particles• All visitors must wear safety glasses in the lab and

areas where chemicals are handled and stored.


Protective Apparel• If the possibility of chemical contamination exists,

personal protective apparel shall be worn.• Lab coats may be worn for protection of clothing

against dirt and minor chemical splashes or spills encountered in the lab, but are not required.

• The choice of protective apparel depends on the degree of protection required.

• Plastic or rubber aprons or full acid suits will be worn with other PPE for protection from corrosive or irritating liquids.

• All protective apparel will be inspected for discoloration, punctures and tears before use.


Hand Protection

• Proper protective gloves will be worn with other protective apparel whenever the potential for contact with corrosive or toxic materials exists.– Latex or latex-free nitrile gloves are appropriate for most

lab applications, but heavier rubber gloves are required for working on plant chemical feed systems and for industrial chemical exposures.

– Insulated gloves will be worn when exposed to thermal hazards.


Eyewash Fountains• Eyewash fountains will be provided in the immediate

area where laboratory chemicals are handled.• An eyewash fountain should provide a soft stream or

spray of aerated water for at least 15 minutes.• Eyewash fountains will be tested at least weekly to

ensure that the eyewash is operable and to remove debris from the system.

• Portable eyewash fountains shall be inspected after each use for quantity of water and availability.


Lab Employee Safety Meetings and Training


Safety Meetings and Training

Each new lab employee will be trained by an experienced employee in the areas of laboratory and chemical safety.

Employees will be provided training to ensure they are aware of hazards and chemicals present in their work area.

All lab employees should attend regular safety meetings with lab staff or with other plant work groups.

Such training will be provided at the time of initial assignment and prior to being exposed to any new exposure situations.

Safety training


Safety measures employees can take to protect themselves from these hazards.

Lab employees are required to attend all of the compliance training provided to all plant employees

Physical and health hazards of chemicals in the work area

This training includes, but is not limited to the use of fire extinguishers, hazard communication.

Methods and observations that may be used to detect the presence or release of hazardous chemicals.

Training will include:
