Neumann University - Chemical
Section 3 Control
Measures date: 7/1/2003
1.0 Control Measures
The intent of control measures is to limit potential
exposure to hazardous chemicals. The exact control measures used must fit the
nature of the hazard and the potential for exposure. The chemistry instructor
or other chemical professional is expected to use their best professional
judgment to determine what specific control measures may be needed to address
any particular situation. In the instructional setting at Neumann the main
control measures are 1) laboratory fume hoods 2) personal protective equipment
3) ventilated chemical storage cabinets and 4) emergency equipment.
3.1 Fume Hoods
Fume hoods should be used when working with:
- Odorous, annoying or irritating materials.
- Volatile solvents where the vapor concentration may
approach the flammable limits.
- Volatile chemicals where the vapor concentration may
approach the TLV.
Fume hoods shall be inspected quarterly as part of the lab
safety inspection to check
1) that the facial velocity is sufficient and 2) that
chemicals are stored properly and without clutter.
3.2 Personal Protective Equipment
- Eye protection. Anyone entering a laboratory is
required to wear eye protection. The minimum required eye protection is
safety goggles with side shield protection. Even casual visitors to the
lab must wear safety goggles. When working with corrosive materials
goggles must provide a tight seal around the eyes.
- Face protection. Full-face shields may be required
or desirable for certain operations such as handling concentrated mineral
acids or in situations were spattering of corrosive materials could occur.
- Protective clothing. In general anyone working in a
lab should wear clothing that minimizes skin exposure. This includes long
sleeve shirts and blouses, long pants and closed shoes. Laboratory aprons
or coats are required whenever corrosive materials, such as mineral acids
or bases, are used.
- Hand protection. Gloves should be worn whenever
there is any possibility of hand contact with corrosive or toxic
materials. Gloves must be chosen that are compatible with the material
being handled and should be inspected before use.
- Respiratory protection. In the instructional
setting at Neumann there should never be a necessity to wear a respirator
as a protective devise. Therefore, respirators are not available.
3.3 Ventilated storage cabinets.
These cabinets are in the storage room within room 345.
Organic chemicals that are liquids are stored in these cabinets. Spill
containment should be used in these cabinets were appropriate.
3.4 Emergency equipment
- Fire extinguishers. These are located at the
entrances of all labs. Annual inspection is the responsibility of the
Neumann University Safety and Security Department. The Laboratory Manager is
responsible for arranging for this inspection.
- Safety shower. The shower, located in room 345,
shall be flushed and checked for proper operation annually by the Neumann
University Facilities Department. The Laboratory Manager is responsible for
arranging for this inspection.
- Eye Wash Stations. The eye
wash stations in each lab must be flushed and checked for proper operation
as part of the quarterly safety inspection.
