Chemical SOP - Acids

IsoLab, Department of Earth and Space Sciences

 

This chemical standard operating procedure (SOP) is for your safety. Read, understand, and follow this document. If this is a paper copy, you should check for the most recent version here: http://isolab.ess.washington.edu/isolab/lab-safety/chemical-sops/4831-chemical-sop-acids. This document was created from a template modeled after the University of Washington Environmental Health and Safety Laboratory Safety Manual Standard Operating Procedures Components, which, as of 160818, is located here. If this link breaks, search the UW website for "chemical sop components".

Are acids particularly hazardous substances? NO (unless using HF, see HF SOP)

What is a particularly hazardous substance? The University of Washington Environmental Health and Safety defines it here.

The SDS for all acids can be found here. You should have taken EH&S Managing Laboratory Chemicals or similarly UW EH&S condoned course.

1. Process Name

Many processes in IsoLab use acids. From washing laboratory glassware to sample carbonate removal. They are prevalent and abundant and lab personnel need to be aware of how to be safe around them.

2. Chemical Name

IsoLab has hydrochloric acid, acetic acid, nitric acid, sulfuric acid, phosphoric acid, and boric acid. We also have hydrofluoric acid, which is given its own SOP here.

3. Personal Protective Equipment

Wear chemical splash goggles and heavy-duty Sol-Vex Nitrile Gloves for concentrated acids. For diluted acids greater than pH 2, use regular purple nitrile gloves. A lab coat or apron is recommended for personal protection.

4. Environmental / Ventilation Controls

Concentrated acids should only be dispensed in a fume hood.

5. Special Handling Procedures & Storage Requirements

When diluting acids, small amounts should be added gradually to water (acid to water, NOT water to acid) and mixed thoroughly to dissipate any heat generated. Acids should be stored separately from bases, oxidizers and flammable solvents. Acids in glass bottles over 1 liter should be transported in spill proof carriers. Acids are stored in 303B corrosive cabinet 1, as well as in 302B corrosive cabinet. Acetic acid is stored in the flammable cabinet 1 in 303B.

6. Spill and Accident Procedures

In case of skin contact, flush affected areas with copious amounts of water for 15 minutes. Obtain medical attention. Neutralize any spilled acids with sodium bicarbonate or spill pads to clean up. Spill kit can be found under sink in labeled cabinets in 302A, 303B, and 302B.

7. Waste Disposal

EH&S has a treatment program for acids and bases; for more information see http://www.ehs.washington.edu/epohazreduce/index.shtm. If disposing of as hazardous waste, label with Hazardous Waste Label, accumulate according to requirements, and send in Chemical Collection Request or Routine Pickup request, both available online at http://www.ehs.washington.edu/epowaste/chemwaste.shtm. Chemical waste is accumulated in the gray secondary containment tubs in 303B near the door.

8. Special Precautions for Animal Use (if applicable)N/A
Particularly hazardous substance involved?NO, ignore 9-11
9. Approval Required

N/A

10. DecontaminationN/A
11. Designated AreaN/A
