INCIDENT AT NC STATE

Wetterhahn knew that dimethylmercury was highly toxic and she took reasonable precautions; she wore safety glasses and latex gloves, and manipulated the chemical in a fume cupboard

Less than a year later, she was dead.

Dimethylmercury penetrated the glove and started entering her skin within 15 seconds.

Today researchers wear highly resistant laminated gloves underneath a pair of long-cuffed neoprene (or other heavy duty) gloves to handle dimethylmercury.

Karen Wetterhahn 1949 - 1997

A Question...

Are Chemical, Biological, and Radiological Hazards the only Hazards of a Lab

Environment ?

Hazard Signs

Subject Specific Training

Radioactive Materials and Equipment Bloodborne PathogensLaser SafetyRespirator UseHearing ConservationOther

ELECTRICAL / MECHANICAL• Know the equipment and energy sources

that you will be using.• Use guarded equipment – avoid pinch pts.• Use ground fault protection• Use double insulated or 3-wire power tools• Lockout Tagout – electrical safety• Obtain training on the equipment that you

will be working with.

Electrical HazardsControl of hazardous energy

NEVER remove some else’s lock and tag from any machine, equipment or device

NEVER try to energize or start any machine, equipment, or device while it is locked or tagged out.You must attend NCSU Lockout Tagout training courses before you apply lockout tagout.

Personal Protective Equipment

Employees must know:When/what type PPE is necessaryHow to properly wearLimitationsMaintenance

Employers must conduct a hazard assessment to determine the PPE needed to conduct each task safely

Hazard assessments conducted for the laboratory are maintained with the safety plan

Tasks completed that are not covered by the safety plan must also be assessed to determine if and what PPE is needed.

Personal Protective Equipment

Eye protection

Gloves

Closed-toe, sturdy shoes

Lab coat

Proper Attire

Safety Glasses

Safety Glasses with side shields

Goggles

Face Shield plus safety glasses

Eye Protection

• Long Sleeves • Easy to remove - buttons• Offers protection against

solids and liquids• Splash – shed coat and

head for shower – leave majority of

contamination behind

Lab Coat

Goggles only Goggles and face shield

• Latex – Avoid powdered and consider latex allergies

• Nitrile – Available in 4 mil thickness – good dexterity

• Other – may need special glove combinations for highly toxic skin penetrants• On-line selection guides

Gloves

Hazardous Material Spill

• Red Light, Yellow Light, Green Light Approach

• Call Campus Police (911) if Yellow or Green

• If necessary, evacuate building
