LABORATORY SAFETY GUIDELINES FOR THE UQU ELECTRICAL ENGINEERING UNDERGRADUATE LAB AREAS IN THE COLLEGE OF ENGINEERING AND ISLAMIC ARCHITECTURE BUILDING
Preamble:
Employers expect that UQU graduates are informed in the environment, safety and health areas that apply to various industries in general and electrical engineering in particular. The university laboratory environment provides a pertinent opportunity to students to experience the expectations of their future professional life, and to practice the required skills. UQU graduates will have higher chances of being employed due to their knowledge of safety of the working environment.
It is the goal of the Electrical Engineering department that all its students complete their studies here at UQU without any personal injury and without any accidents that affect the environment adversely.
Electrical Engineering Department expects all students, visitors, staff and faculty to adhere to all Laboratory Safety Guidelines when present in all Electrical Engineering laboratories at all times.
General Laboratory Safety Rules:
Footwear: No one is allowed to enter in the lab area bare foot due to increased risk of electric shock.
Food, Beverages and Smoking: Due to the fact that maintenance of the lab equipment including calibration and repair is expensive and due to the increased risk of electric shock, absolutely no drinking of beverages or consumption or storage of any kind of food is allowed in the laboratory.
Smoking is prohibited in all laboratories at all time.
Dress: Appropriate apparel shall be worn in laboratories at all times.
Soldering: No one is allowed to do soldering in any of the electrical engineering laboratories except the graduation design project laboratory. Anyone doing soldering in the graduation design Project laboratory area must wear appropriate apparel, socks, gloves, covered shoes and safety goggles. This is to prevent the possibility of severe burns resulting from the splashing or dripping of hot liquefied solder into the face and eyes or on to the exposed skin on the chest, hands, legs, and feet. Students who are not so properly attired for these tasks will NOT be allowed to perform any type of soldering in the graduation Design project laboratory area.
Emergency:
Police, Fire or Medical Emergency: Use the telephone located in the laboratory area and press 9-9-6 to notify police, fire, and ambulance for emergency help.
Everyone present in the laboratory area shall be familiar with the locations and operation of safety and emergency equipment, including but not limited to, fire extinguishers, first aid kits, emergency power off system, fire alarm pull stations, and emergency telephones.
Learn and know what to do in an emergency!!
Building Evacuation:
Everyone present in the laboratory area shall be familiar with the emergency exits and way out plans.
Use the nearest exit doorway from lab area closest to the stairwell to exit the building.
Follow the Emergency Exit Signs posted in the hallways. Do not use elevators.
NOTE: Lab Teaching Assistants (TAs) or Instructor shall make sure all persons are out of the laboratory area and follow the directions posted at each doorway to the laboratory area.
Laboratory Equipment:
Lab equipment may not be removed from the Electrical Engineering lab areas without the permission of the Laboratory Supervisors. Laboratory bench equipment (except for some lab bench computers) must be turned off before closing down the lab area for the day.
Never open (remove cover) of any equipment in the laboratories. Never "jump," disable, bypass or otherwise disengage any safety device or feature of any equipment in the laboratories.
Laboratories shall be locked when unoccupied.
Electrical Safety Guidelines
Laboratory Operating Hours: Students are never allowed to work alone in any lab area outside of the scheduled laboratory operating hours unless either a Lab TA or Course Instructor is present inside that lab area. The laboratory operating hours for students are posted on the entrance doorway and on the notice board of electrical engineering department. There is a Lab TA on duty in the lab during the operating hours.
Laboratory Access: Students shall access the electrical engineering laboratory areas only through the main entrance located at the laboratory doorway.
Personnel Safety:
Be familiar with the electrical hazards associated with your workplace.
Be as careful for the safety of others as for yourself. Think before you act.
Be tidy and systematic.
Avoid bulky, loose or trailing clothes. Avoid long loose hair.
Remove metal bracelets, rings or watchstraps when working in the laboratories.
Food, beverages and other substances are strictly prohibited in the laboratory at all times.
Avoid working with wet hands and clothing.
Equipment accessories:
Use extension cords only when necessary and only on a temporary basis.
Request new outlets if your work requires equipment in an area without an outlet.
Discard damaged cords, cords that become hot, or cords with exposed wiring.
Equipment Safety:
Before equipment is energized ensure, (1) circuit connections and layout have been checked by a Teaching Assistant (TA) and (2) all colleagues in your group has given their consent.
Experiments left unattended should be isolated from the power supplies. If for a special reason, it must be left on, a barrier and a warning notice are required.
Equipment found to be faulty in any way should be reported to the lab supervisor and taken out of service until inspected and declared safe.
Waste Management:
Know the correct handling, storage and disposal procedures for batteries, cells, capacitors, inductors and other high energy-storage devices.
Power Supplies Related Safety:
Voltages above 50 V rms AC and 120 V DC are always dangerous. Extra precautions should be considered as voltage levels are increased.
Never make any changes to circuits or mechanical layout without first isolating the circuit by switching off and removing connections to power supplies.
Know what you must do in an emergency!!!
Emergency Power Off:
Every lab is equipped with an Emergency Power Off System. When this switch is depressed, electrical power to the lab will shut off, except for the lights. Only authorized personnel are permitted to reset power once the Emergency Power Off system has been engaged.
Electrical Emergency Response:
The following instructions provide guidelines for handling two types of electrical emergencies:
1. Electric Shock:
When someone suffers serious electrical shock, he may be knocked unconscious. If the victim is still in contact with the electrical current, immediately turn off the electrical power source. If you cannot disconnect the power source, depress the Emergency Power Off switch.
IMPORTANT!!
Do not touch a victim that is still in contact with a live power source; you could be electrocuted!!!
Have someone call for emergency medical assistance immediately. Administer first-aid, as appropriate.
2. Electrical Fire:
If an electrical fire occurs, try to disconnect the electrical power source, if possible. If the fire is small and you are not in immediate danger; and if you have been properly trained in fighting fires, use the correct type of fire extinguisher to extinguish the fire. When in doubt, push in the Emergency Power Off button.
DANGER!!
NEVER use water to extinguish an electrical fire!!!
The above general laboratory safety rules are designed to safeguard you and your co-workers, fellow students and colleagues and are a minimum requirement for individuals working in the electrical engineering laboratories at Umm Al-Qura University, Makkah Al-Mukarramah. Specialized training and rules may apply depending on type and scope of activities involved.
