The science laboratories of Dubai Carmel School are spacious, neat, tidy and well equipped with latest scientific instruments and apparatus. It is mandatory for all science students to experience practical skills in their relevant subjects. The best safety measures make the place a safe place.
The below given rules are followed during laboratory classes;
Safety Standards of Student Conduct in the Classroom, Laboratory, and in the Field:
To conduct oneself in a responsible manner at all times. Frivolous activities, mischievous behaviour, throwing items, and conducting pranks are prohibited.
Lab and safety information and procedures must be read ahead of time. All verbal and written instructions shall be followed in carrying out the activity or investigation.
Eating, drinking, gum chewing, applying cosmetics, manipulating contact lenses, and other unsafe activities are not permitted in the laboratory
Working in the laboratory without the instructor present is prohibited.
Unauthorized activities or investigations are prohibited. Unsupervised work is not permitted.
Entering the preparation or chemical storage areas is prohibited at all times.
Removing chemicals or equipment from the classroom or laboratory is prohibited unless authorized by the instructor.
Sanitized indirectly vented chemical splash goggles or safety glasses as appropriate shall be worn during activities or demonstrations in the classroom, laboratory, or field, including pre-laboratory work and clean-up, unless the instructor specifically states that the activity or demonstration does not require the use of eye protection.
When an activity requires the use of laboratory aprons, the apron shall be appropriate to the size of the student and the hazard associated with the activity or investigation. The apron shall remain tied throughout the activity or investigation.
All accidents, chemical spills, and injuries must be reported immediately to the instructor, no matter how trivial they may seem at the time. Follow your instructor’s directions for immediate treatment.
Dress appropriately for laboratory work by protecting your body with clothing and shoes. This means that you should use hair ties to tie back long hair and tuck into the collar. Do not wear loose or baggy clothing or dangling jewelry on laboratory days. Acrylic nails are also a safety hazard near heat sources and should not be used. Sandals or open-toed shoes are not to be worn during any lab activities.
Know the location of all safety equipment in the room. This includes eye wash stations, the deluge shower, fire extinguishers, the fume hood, and the safety blanket. Know the location of emergency master electric and gas shut off and exits.
Biology Lab may have living organisms including plants in aquarium or other containers. Students must not handle organisms without specific instructor authorization. Wash your hands with soap and water after handling organisms and plants.
When an activity or investigation requires the use of laboratory gloves for hand protection, the gloves shall be appropriate for the hazard and worn throughout the activity.
Avoid inhaling fumes that may be generated during an activity or investigation.
Never fill pipettes by mouth suction. Always use the suction bulbs or pumps.
Do not force glass tubing into rubber stoppers. Use glycerin as a lubricant and hold the tubing with a towel as you ease the glass into the stopper.
Proper procedures shall be followed when using any heating or flame producing device especially gas burners. Never leave a flame unattended.
Remember that hot glass looks the same as cold glass. After heating, glass remains hot for a very long time. Determine if an object is hot by placing your hand close to the object but do not touch it.
Should a fire drill, lockdown, or other emergency occur during an investigation or activity, make sure you turn off all gas burners and electrical equipment. During an evacuation emergency, exit the room as directed. During a lockdown, move out of the line of sight from doors and windows if possible or as directed.
Always read the reagent bottle labels twice before you use the reagent. Be certain the chemical you use is the correct one.
Replace the top on any reagent bottle as soon as you have finished using it and return the reagent to the designated location.
Do not return unused chemicals to the reagent container. Follow the instructor’s directions for the storage or disposal of these materials.
Standards For Maintaining a Safer Laboratory Environment:
Backpacks and books are to remain in an area designated by the instructor and shall not be brought into the laboratory area.
Never sit on laboratory tables.
Work areas should be kept clean and neat at all times. Work surfaces are to be cleaned at the end of each laboratory or activity.
Solid chemicals, metals, matches, filter papers, broken glass, and other materials designated by the instructor are to be deposited in the proper waste containers, not in the sink. Follow your instructor’s directions for disposal of waste.
Sinks are to be used for the disposal of water and those solutions designated by the instructor. Other solutions must be placed in the designated waste disposal containers.
Glassware is to be washed with hot, soapy water and scrubbed with the appropriate type and sized brush, rinsed, dried, and returned to its original location.
Goggles are to be worn during the activity or investigation, clean up, and through hand washing.
