Heated Liquids Safety

Standard Operating Procedures

Building: Combs Research Building
Room: 222
Department: Markey Cancer Center
PI: Andrew Pierce, PhD.

Section 1: Process

Section 2: The purpose of the Heated Liquids Safety module is to be used as a guideline to ensure the laboratory worker remains cognizant of the liquids used in the labs and their associated hazards when heated. Heated liquids incorporates the use of the autoclaves, water baths, heat blocks, and also heating liquids via microwaves and heat stir plates.

Section 3: The most common hazards when working with heated liquids are thermal burns. Sometimes, however, it is possible to super-heat some liquids beyond their natural boiling point. Such super-heated liquids may boil suddenly and violently when jolted or stirred after removal from a microwave oven or autoclave. It is therefore a good idea to take the necessary precautions such as covering liquids or allowing them to cool before removal from the heat source *OTHERWISE SERIOUS BURNS WILL OCCUR.

Burns are thereby classified on the amount of damage: 1st, 2nd or 3rd degree.

Section 4: All lab personnel should be wearing a lab coat or lab apron, gloves and safety glasses when working with heated liquids in the lab, at a minimum. Orange autoclave gloves should be worn when working with hot liquids out of the autoclave, and the rubberized Hot Hand gripper should be used to handle hot liquid filled flasks from the microwave.

Secton 5: The engineering controls for this module will be the use of the safety shower and eyewash station located by the sink in the lab.
A first aid kit is located on the computer bench top shelf if needed.

Section 6: The microwave is stored to the left of the entryway. Heat blocks will be located throughout the lab as well as heat stirrers. The one water bath that we have is located on the right side of the entryway. All autoclaves will be located on the 2nd floor in room 229. Access to the lab shall be limited (room securely locked when unoccupied) to laboratory personnel only.

Section 7: If a spill from a heated liquid should occur, clean up the liquid after its cooling according to its hazard rating and dispose of the towels into the biohazard container. If the laboratory worker was burned, they should seek treatment immediately going to the UK emergency room or by dialing 911.

Section 8 & 9: For decontamination purposes, a solution of 1% Alconox or 10% Bleach will be sufficient to cleanse the area where the spill occurred making sure that there is a 20 minute contact period. Once the area is free from contaminants from the spill, 70% ETOH can be applied to the area and then wiped clean with paper towels. Any glass should be disposed of into the sharps container while all towels should be placed in the biohazard container both provided in the lab.

So called Anonymous: I htnesoly guessed it was you. You have a habit of not writing your name when you think someone might disagree with you, but I'm really not thick.. Firstly, you don't know me so you don't know what I am and am not conforming to and secondly somebody who is using a pure, perfect religion to kill innocent people (and there were Muslims on that plane) and tarnish the name of Islam deserves to be called worse. I don't understand how you can call him a fellow Muslim at all? What's wrong with you? And also what is your issue with white people man? Maybe you should go live in Saudi for a bit and then compare how you're treated there to how white people treat you.WassalamP.S. Of course Muslim women have it worse. You could still be a hindi with a beard.
