Safety in the laboratory – An toàn trong phòng thí nghiệm

Safety in the laboratory – Đồ án môn học chuyên ngành Hóa – Sinh: An toàn trong phòng thì nghiệm

With safety in the laboratory, before conducting any experiment, you should access the hazards related to the work, including; what are the worst possible things that could go wrong, how to deal with them, and what are the prudent practices, protective facilities and equipment necessary to minimize the risk of exposure to the hazards.

Always know the hazards of the materials used (e.g., corrosivity, flammability, reactivity, and toxicity). Use the Project Hazard Review Checklist (in Adobe PDF format) to help you with this assessment.

Read the Material Safety Data Sheets (MSDS) for information on all chemicals you plan to use. Make sure all Personal Protective Equipment (PPE) is on hand. Use the MSDS or Personal Protective Equipment Selection Guide (in Adobe PDF format) to select the needed equipment

Part 1 : Basic aspects

Working hours

Working hours are Monday through Friday between 7h00 and 19h00 outside these times

– It is forbidden to do experimental work alone in a lab (a colleague must be within earshot!)

– The responsible professor must be informed and he must   explicitly authorize high-risk experiments between 7h00 and 20h00, the technical staff can intercept alarms during nights, weekends and holidays, all alarms are directly transmitted to the fire brigade

1. Plan Your Work

It is mandatory to

– wear safety goggles

– wear a labcoat that is closed in the front

– tie up long hair

– wear appropriate gloves when manipulating dangerous substances (see later)

– wear closed shoes (no sandals, flipflops etc.)

Post a sign on the door to notify others of the lab hazards and list emergency contact numbers.

Inspect equipment and apparatus for weaknesses, cracks or damage before beginning work.

Inspect electrical equipment and cords for frayed wiring or damage before use. Discard or repair damaged equipment before use.

2. Behavior in the laboratory with safety in the laboratory

In the laboratory it is forbidden to

– eat or drink  (let alone smoke!)

– wear inappropriate clothes (shawls, blouses or shirts   with loose sleeves or from easily flammable fabrics)

– wear a headphone to listen to music (alarms!)

– work without a colleague being in hearing distance

– wear contact lenses (safety goggles with optical lenses   are made available at no cost to permanent staff)

– bring to or take out chemical products from the building with safety in the laboratory
