IV. Evacuation Plan
1. Types of Evacuation

a. General - all building occupants must evacuate.
b. Local - occupants of the lab (123C) must evacuate.

The General Evacuation routes for the rooms associated with this lab are marked on the
Evacuation Plan map shown on the previous page. Personnel working in Room 123 C should
follow the evacuation route in the map and exit to the east parking lot of D.S. Weaver Labs. The
east parking lot of Weaver labs is the designated meeting area in the case of an emergency. If the
marked evacuation route is blocked, a alternative route is to exit directly to the outside through
the roll up door. The roll up door is open manually by pulling on the chain. Occupants will be
advised by Public Safety when it is safe to return. Whenever possible, turn off all electrical
power. The main electrical load center is located in the hall way leading to and just outside of
room 123C. There are NO gas lines in room 123C. Local Evacuations do not require exit from
the building. Avoid hindering any emergency operations in progress. In any evacuation, do not
leave the designated meeting area. Your absence will be interpreted that you are still in the
danger area and one or more persons may risk their lives looking for you.

2. Situations Requiring Evacuation

a.. Fire of any nature. Activate the fire alarm and proceed with general evacuation of building.
Telephone Public Safety (5-3333) from another building immediately.

b. Chemical Spills - N/A. No Hazardous Chemicals are permitted in room 123C. Such spills as
may occur should be relatively small in volume, and may not require evacuation. If there is any
doubt concerning the severity of the spill or accident, evacuate the lab.

c. Power interruptions. Immediately proceed with local evacuation. Close lab entrance door. Do
not enter room until after power is restored.

The Evacuation Route from room 123C is shown on the following page.

6. Special Handling and Storage Requirements
No materials are to be brought into this laboratory unless it is directly related to the project of
interest. No materials such as paints, adhesives or lubricants are to be discarded in the sink drain.

7. Spill and Accident Procedures
Before starting work, each worker is to make certain the following items are available in the
        absorbent materials such as vermiculite and paper towels,
        brush and dust pan,
        plastic bags of different sizes,
        a sealable container (metal can or plastic lined box).

When handling chemicals, always wear lab apron, safety glasses, filter-mask, and latex gloves as
appropriate. In case of minor spills, place the absorbent material over the spill and ventilate the
area by opening the hall door or the roll up door. If the spill generates odor, open the roll up door
and step outside Room 123C into the hall way and ask other workers to accompany you. Make
sure the hall-way door is closed to prevent the odor from entering the rest of the building. It may
be necessary to place an additional fan near the hallway door and ventilate such that air is
blowing from the room toward the parking lot. Return to the spill area after all odor is ventilated
and gently brush the absorbent materials to a lift-pan and dispose off them into the designated
container, and seal the container. In the case of minor spills, wash the spill area thoroughly with
a wet paper towel and discard these towels with the adsorbent materials.

In case of a major (ODOROUS OR OTHERWISE) spill, immediately vacate the spill area and
ask other occupants to accompany you. It may be necessary to alert occupant of the adjoining
rooms (123A and 123B) to vacate those rooms also. Call the EH&S (5-6858) immediately. Do
not attempt to manage the spill yourself. If you feel that the spill is dangerous, also call the
emergency number 5-3333. (DO NOT attempt to use the phone near the laboratory under above

                                                   Page 9 of 20
1. General Statement
Each person working in room 123C (faculty, staff, graduate and under graduate students) will be
required, as necessary, to take safety courses offered by various safety personnel of the
university. In addition, each authorized worker will be trained in the two areas of physical
hazards and chemical hazards before they can start work in the laboratory. The training will be
individualized in that the rigor will depend on the prior experience and duties of each worker.
Each person trained will be required to sign the Safety Training Certification Form, as shown

Additionally, the safety information contained in this manual will be available in room 123C for
ready reference at all times. Each person working in room 123C is instructed to contact the
Principal Investigator immediately at any time they do not understand a procedure, observe a
potential safety problem or have a question or concern about laboratory rules or procedures.

2. Safety Training Procedure
The following steps shall be standard training practices and procedures for all teaching
laboratories in the Biological and Agricultural Engineering Department:

a. The person in charge (Principal Investigator) of the teaching laboratory will be responsible for
keeping the safety plan for that area up-to-date and responsible for reviewing the plan with each
person teaching or assisting in instruction.

b. The instructor will be responsible for providing safety instruction for each class. The
following item will be included:

  (i) A brief statement of safety policy and procedures will be a part of the course syllabus,
  outline or assignment sheet and be handed out the first day of class. Also, this statement will
  be explained orally to the students.

  (ii) This safety plan will be reviewed and explained to students prior to their use of laboratory
  facilities. General safety precautions will be reviewed and be included as subject matter for

   (iii) Safety instruction will be provided for each major piece of equipment to be used by the
   students. Specific hazards, unique to each piece of equipment, will be covered in detail.
   Information from the appendix of the safety plan as well as the equipment manufacturers
   safety instructions will be included as appropriate. Hand and small power tools may be stored
   and used in this area. Operators of such tools must always read and understand the applicable
   instruction manual before using the tool to become familiar with its operation and associated
   hazard and safety. When available, the instruction manuals will remain near the instruments at
   all times.
c. The instructor will be responsible for a safety check of the teaching area prior to and after
class to see that housekeeping is adequate from a safety standpoint and that safety equipment is

                                          Page 10 of 20
in place. This duty may be delegated as a specific responsibility of a teaching technician or
teaching assistant.

d. At the end of the semester the safety plan will be reevaluated by the instructor and teaching
assistant to identify any new concerns that may have arisen and to make appropriate

X. General Safety Guidelines
1. General Statement. Carelessness is the major cause of many accidents in a fabrication shop.
These accidents often result in pain, serious injury and the loss of time, money, productivity, and
can result in damaged tools or equipment. With proper precautions, most accidents may be

The first line of defense against an accident is the operator of the piece of equipment. Although
every possible hazard cannot be anticipated, having a healthy respect for the unknown as well as
the known hazards can significantly reduce the likelihood of injury or damage. The capabilities
and limitations of the operator as well as the machine must be recognized and accommodated.
This is true for the simplest shop equipment as well as the most the most complex machines.
 Proper training and experience is the key to accident prevention.

2. General Procedural and Housekeeping Rules

a. Although Limited eating and drinking is permitted in this laboratory, you should avoid any
situations where there is a possibility of contaminating the food, food containers, drinking
containers, and hands with toxic or hazardous substances. The refrigerator in this lab is for food
storage only. No non-food items or chemicals are permitted.

b. There is NO Smoking permitted in room 123C at any time. Smoking is permitted only in
properly designated smoking areas.

c. It is advisable not to work alone when you are performing functions that involve power tools
or potentially hazardous devices. There should be at least one other person within earshot who
knows you are working in the lab and who can provide assistance in an emergency, or call for
help if the need arises.

d. Durable and appropriate quality work clothing is required. Your project work may require
you to soil your hands and clothes. Lab aprons are available and you are urged to avoid any
clothes that may become entangled in moving machines. It is also advisable to remove all
jewelry such as watches, rings, and necklaces.

e. Horseplay is never permitted. Equipment must be used for their intended purpose only.

f. Bench and counter tops must be kept clear of any devices or materials not directly related to

                                          Page 11 of 20
the experiment in progress. All work surfaces must be brushed clean or wiped down with a damp
paper towel immediately following use.

g. All tools must be cleaned and replaced into their proper cabinet or drawer after use. Report
missing tools promptly to the instructor or teaching assistant.

6. Additional Rules for Electrical Safety

                                            Page 13 of 20
a. Do not touch a person in contact with a live electrical circuit. Disconnect the power first or
you may be seriously injured.

b. All laboratory personnel should know the location of circuit breakers and how to cut off all
electrical service to the laboratory in case of fire or accident.

c. All electrical outlets should carry a grounding connection requiring a three-pronged plug.

d. All electrical equipment should be wired with an approved grounding plug. If equipment does
not have a three-pronged plug, the equipment must be separately grounded. All electrical outlets
should be periodically checked for proper grounding.

e. Continuity of grounding connections, including leads to building ground
itself, should be checked periodically by an authorized inspector.

f. Follow the National Electrical Code in all installations. The installation of all wiring must only
be done by appropriate university personnel. This includes proper grounding as well as
installation of proper equipment service for laboratory areas. Grounding electrical outlets may
not be enough protection in a laboratory where the floor might be wet or where there is much
electrical equipment. In these cases, an approved ground-fault interrupter may be required.

g. Do not use wiring that is frayed or worn. If possible, do not use drop cords or allow wiring to
lie unprotected on the floor. Panel boards and electrical outlets should be properly labeled and
never have missing cover plates or other parts.

h. The condition of wiring, plugs, cords, and related equipment should be regularly inspected.
Display warning signs on or near the main power switch of each electrical device.

i. Refrigerators constitute a unique hazard because explosions may occur when
they are used for storage of volatile or unstable chemicals. (No flammable liquids are to be
stored in this laboratory.) The household-type refrigerators in room 134D must be used for the
storage of dry chemicals only. No food or drink is permitted in this lab.

7. Vacuum

The term "vacuum" refers to the condition of an enclosed space that is devoid of air or
other gases or other material content. It is not experimentally feasible in a terrestrial
environment to achieve a complete or "perfect" vacuum, although by modem techniques one can
approach this condition closely. The degree of vacuum is normally measured in units of Atorr@(
1 torr = 1/760 of a standard atmosphere) or the degree of vacuum may be expressed simply in the
height of a column of mercury the vacuum will support. AHard@ or high vacuums may be in
terms of millionths of a millimeter of mercury . Most vacuums used in the laboratory are less
than "hard" and may be in the range of tenths or hundredths of a millimeter of mercury. For
many routine purposes a "utility vacuum" or "fore pump vacuum" will suffice, and for vacuum

                                           Page 14 of 20
distillations only a "partial vacuum" of the order of 1 to 50 torr is needed.

Vacuum apparatus may present significant hazards which are summarized below:

a. Implosion: This hazard is most important with glass apparatus, and is ever present when large
glass bulbs (over one liter *in size) or flat bottom vessels (of any size) are evacuated. The force
of atmospheric pressure makes dangerous missiles of glass fragments from imploding vessels.
Where possible, avoid evacuating flat-bottomed vessels. Reduce the hazard of flying glass by
placing strips of plastic electrician's tape on all large glass vessels that are to be evacuated.

b. Explosion. If in a vacuum system significant quantities of a gas have been liquefied, or taken
up by an absorbent at low temperature, an explosion can result when the system warms up if
adequate vents or safety valves have not been provided. An explosion of a different kind can
take place if an oil diffusion pump (particularly a glass one) is
vented to air while hot.

c. Liquid air (liquid oxygen). Liquid air boils at a higher temperature than liquid nitrogen (about
900K vs. 770K) and can easily be condensed with liquid nitrogen refrigeration at one
atmosphere. No liquified gases are to be used or stored in this laboratory.

d. Mercury poisoning. Mercury diffusion pumps, McLeod gauges, mercury manometers and
thermometers all pose hazards of mercury contamination of the environment in the event of
fracture of the glass apparatus. Remember that the room-temperature vapor pressure of mercury
exceeds by two orders of magnitude the maximum allowable concentration of mercury in room
air. Regularly inspect all mercury containing devices. Try to keep them in a plastic pan of
sufficient volume to hold all of the mercury in case the device should break. Check with EH&S
(5-6858) for mercury monitoring or for help with a mercury spill.

e. Glass tubing. When pushing a glass tube through a rubber stopper, protect your hands with a
towel or canvas gloves. Always hold the glass close to the end being inserted. Glycerin or
another lubricant should always be used.

f. Vacuum desiccators should be enclosed in a box or approved shielding device for protection in
case of an implosion. Only chemicals being dehydrated to be kept dry should be stored in a
desiccators. When opening a desiccator that is under vacuum, make sure that atmospheric
pressure has been restored. A "frozen" desiccator lid can be loosened by using a single-edge
razor blade as a wedge, which is then tapped with a wooden block to raise the lid.

g. Water aspirators for reduced pressure are used mainly for filtration purposes, and only
equipment that is approved for this purpose should be used. Never apply a vacuum to a
flat-bottomed flask unless it is very small or it is a heavy-walled filter flask designed for the
purpose. Place a trap and a check valve between the aspirator and the apparatus so that water
cannot be sucked back into the system if the water pressure should fall
unexpectedly while filtering. These recommendations also apply to rotary evaporation operations

                                           Page 15 of 20
where water aspirators are being used for vacuum.

h. Mechanical & electrical hazards. The belt drive of a mechanical pump may catch loose
clothing, hair, etc. All belt drives must have an appropriate belt guard in place during use. Check
all electrical cords. Replace any that are frayed. Be sure all plugs are 3-prong and that all sockets
are correctly wired. Replace any cracked or broken switch casings.

8. Noise Exposure

No equipment or processes in room 123C produces excessive noise, although this location might
be exposed to occasional noise produced through ongoing engineering research in the adjoining
areas. You should therefore be familiar with the following and bring to the attention of the
instructor when you feel hazardous noise levels exist in your work environment.

XI. Reporting Laboratory Accidents
All accident which result in injury, however minor, result in excessive exposure to hazardous
materials or are considered near misses are to be reported immediately to the Instructor or
Teaching Assistant and to Public Safety (515-3333) / NCSU Environmental Health and Safety
Center (515-6858). Spills of hazardous materials or other situations that are potentially
hazardous are also to be reported immediately.

A written accident report must be completed by the person(s) involved in the accident, if
possible, within 24 hours of the occurrence of the accident. Copies of the report are to filed with
the instructor who will promptly forward copies to the department head and to the NCSU
Environmental Health and Safety Center. The accident form below should be used for this
purpose. Copies of completed accidents forms and blank copies of this form will be maintained
in the Lab Safety Manual.

Accidents involving students or others who are not employees, do not require Worker's
Compensation reporting.

Employees Only: Accident/Illness Worker's Compensation forms are available from NCSU
Environmental Health and Safety Center. Completely fill out both forms and return WITHIN
FIVE (5) DAYS following the accident.

Guidelines for Selecting Personal Protective Equipment (PPE)

Note: PPE alone should not be relied on to provide protection against hazards, but should be
used in conjunction with guards, engineering controls and sound manufacturing practices.

1. Familiarize yourself with the potential hazards in the are and the types of PPE that are

2. Consider the hazards associated with the environment (impact velocities, masses, projectable
shape, radiation intensities)

3. Select PPE that ensures a greater level of protection than the minimum required to protect
workers from the hazards.

4. Fit the worker with the PPE and give instructions on its use and care. It is very important that
workers be made aware of all warning labels for and limitation of their PPE.

Based on the hazard assessment for        Construction of Student Design Projects,
the following PPE is required:

      EYE HAZARD                             JOB                             PPE
