Takeaways

• 😀 Always follow safety rules when working in laboratories, including wearing appropriate protective gear like long-sleeve lab coats, safety goggles, and gloves.
• 😀 Before using any chemical product, consult the safety data sheet and understand emergency procedures, such as using fire extinguishers or emergency showers.
• 😀 In case of chemical spills, use an emergency kit to contain the spill and properly dispose of contaminated materials by labeling and disposing them in black or gray bags.
• 😀 Ensure the proper storage of chemicals by following the chemical incompatibility table and regularly updating the chemical inventory every six months.
• 😀 Secondary labeling is required for any containers with chemicals that have been fractioned, ensuring correct usage and preventing mistakes.
• 😀 Special attention is needed when handling liquid fuels and flammable chemicals, including proper storage containers, secondary labeling, and site signage.
• 😀 Cylinders of gas must be stored upright and secured to prevent accidents, and only trained personnel should handle their refilling.
• 😀 Hazardous waste, including chemicals and medical waste, must be properly labeled and stored in designated containers, following safety protocols.
• 😀 The disposal of hazardous waste, especially from the health sector, requires specific labeling and correct treatment, such as thermal treatment for medical waste.
• 😀 Laboratories must perform regular inspections of safety equipment such as fume hoods, eyewash stations, and emergency showers to ensure they are functioning correctly.

Q & A

What are the primary safety rules when working in a laboratory at Unisinos?

The primary safety rules include wearing long-sleeved lab coats or aprons, long pants, closed shoes, safety goggles, and gloves. Additionally, food and drinks are prohibited inside the laboratory.

How should chemical spills be handled in the laboratory?

In the case of a chemical spill, use the emergency kit to contain the spill. Spread sand or sawdust around the spilled liquid until it is fully absorbed. Then, collect the contaminated waste and dispose of it in black or gray plastic bags labeled with the waste classification.

What is required for the proper storage of chemicals in the laboratory?

Chemicals should be stored according to the chemical incompatibility table, which can be found on the MiniSinos portal. Regular updates of the chemical inventory are mandatory every six months.

What should be done if the laboratory works with controlled substances?

If working with controlled substances, the laboratory must fill out forms F44 and F68 monthly and submit them by the first business day of the month to the designated email ([email protected]).

How should secondary labeling be applied to chemical containers?

Secondary labeling should be applied to containers holding fractional amounts of chemicals. The label should include the original product information to prevent misuse.

What should be done if a laboratory generates hazardous waste?

Hazardous waste, including chemical solids, liquids, and biological samples, must be properly identified and stored in appropriate containers. Solid waste should be placed in black or gray plastic bags or cardboard boxes, while liquids should be stored in 20-liter drums or various bottles.

How should laboratory waste be disposed of?

Laboratory waste should be clearly labeled and segregated according to its type. For certain hazardous wastes, such as inorganic influents, neutralization must occur before disposal. The waste should be collected by the waste disposal service by emailing [email protected].

What are the guidelines for using a fume hood in the laboratory?

When using a fume hood, ensure that the exhaust system is functioning, and keep the hood and bench clean. Remove any unnecessary materials, especially toxic and flammable chemicals. If the exhaust stops, inform colleagues, close the window, and request repairs.

What are the rules regarding the use and storage of gas cylinders in the laboratory?

Gas cylinders must be stored upright and secured with chains. Only trained personnel are allowed to handle the cylinders. The storage area must be properly signposted to indicate the presence of hazardous materials.

What should a laboratory do if it needs to dispose of used glassware or damaged lab equipment?

Used glassware and damaged equipment should be placed in designated collectors for glass. Afterward, they should be sent to the glassware laboratory for repair and returned to the appropriate sector.
