5. SAFETY
5.1 Safety precautions must be taken when handling reagents, samples and
equipment in the laboratory. Protective clothing including lab coats,
safety glasses and enclosed shoes should be worn. In certain situations, it
will be necessary to also use gloves and/or a face shield. If solutions come
in contact with eyes, flush with water continuously for 15 minutes. If
solutions come in contact with skin, wash thoroughly with soap and water.
Contact Solomons Rescue Squad (911) if emergency treatment is needed
and also inform the CBL Business Manager of the incident. Contact the
CBL Business Manager if additional treatment is required.
5.2 The toxicity or carcinogenicity of each reagent used in this procedure may
not have been fully established. Each chemical should be regarded as a
potential health hazard and exposure should be as low as reasonably
achievable. Cautions are included for known hazardous materials and
procedures.
5.3 Do not wear jewelry when troubleshooting electrical components. Even
low voltage points are dangerous and can injure if allowed to short circuit.
5.4 The following hazard classifications are listed for the chemicals used in
this procedure. Detailed information is provided on Material Safety Data
Sheets (MSDS).
On a scale of 0 to 4 the substance is rated on four hazard categories: health, flammability,
reactivity, and contact. (0 is non-hazardous and 4 is extremely hazardous)
STORAGE
Red – Flammability Hazard: Store in a flammable liquid storage area.
Blue – Health Hazard: Store in a secure poison area.
Yellow – Reactivity Hazard: Keep separate from flammable and combustible materials.
White – Contact Hazard: Store in a corrosion-proof area.
Green – Use general chemical storage (On older labels, this category was orange).
Striped – Incompatible materials of the same color class have striped labels. These
products should not be stored adjacent to substances with the same color label. Proper
storage must be individually determined.
