M10.2 Blog about MSDS and ToxNet

I work in a lab and we have a MSDS on the chemical sulfuric acid. These are the current health risks associated with the chemical:

  • Eye Contact: Check for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Cold water may be used. Get medical attention immediately. 
  • Skin Contact: In case of contact, immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Cover the irritated skin with an emollient. Cold water may be used.Wash clothing before reuse. Thoroughly clean shoes before reuse. Get medical attention immediately. 
  • Serious Skin Contact: Wash with a disinfectant soap and cover the contaminated skin with an anti-bacterial cream. Seek immediate medical attention. Inhalation: If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention immediately. 
  • Serious Inhalation: Evacuate the victim to a safe area as soon as possible. Loosen tight clothing such as a collar, tie, belt or waistband. If breathing is difficult, administer oxygen. If the victim is not breathing, perform mouth-to-mouth resuscitation. 
  • Ingestion: Do NOT induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an unconscious person. Loosen tight clothing such as a collar, tie, belt or waistband. Get medical attention if symptoms appear. 
  • Serious Ingestion: Not available.


Chemical carcinogens are any substance or radiation that promote carcinogenesis, the formation of cancer. Chemicals found in my workplace I would be trained on personal protection and in case of a large spill as well. I would also take special courses about the chemical and ensure that I fully equipped with handing this chemical. These are the personal protection precautions:

  • Engineering Controls: Provide exhaust ventilation or other engineering controls to keep the airborne concentrations of vapors below their respective threshold limit value. Ensure that eyewash stations and safety showers are proximal to the work-station location. 
  • Personal Protection: Face shield. Full suit. Vapor respirator. Be sure to use an approved/certified respirator or equivalent. Gloves. Boots. 
  • Personal Protection in Case of a Large Spill: Splash goggles. Full suit. Vapor respirator. Boots. Gloves. A self contained breathing apparatus should be used to avoid inhalation of the product. Suggested protective clothing might not be sufficient; consult a specialist BEFORE handling this product.

There are no discrepancies in the MSDS and ToxNet reporting. If anything the ToxNet database is much more elaborate on the health effects of the chemical. Here is the information about the chemical: https://toxnet.nlm.nih.gov/cgi-bin/sis/search2/f?./temp/~ajpHga:3

The potential dangers of this chemical is just handling and usage. You must use the proper chemical protection when handling it in the lab. The MSDS was an adequate tool for a worker to gain understanding of the risks. We want to make sure that we are protected when using this chemical and if there is a spill. The MSDS is a simple and useful tool for anyone to use and I liked that it is available for any person.

  1. Hi Snay,
    Thanks for your post. Its great that you didn't find any discrepancies in the MSDS and ToxNet reporting. I agree with you the information provided by ToxNet is more in depth.

  2. Hi Snay,

    Thanks for sharing! I'm delayed on some of my blogs, so I'm interested in learning how easy it was for you to access your MSDS. I plan to request mine at work and I'm assuming I would possibly ask our facilities manager for it. Where there any chemicals on there that stood out to you as unexpected?

    I feel like sulfuric acid is common in a lab setting. After reading about the multiple forms of harmful exposure, I'm wondering whether you feel like you have all of the tools to address these multiple forms of exposure within your work place. Sometimes I feel like even though everything is available, many times employees do not know where to find these tools.
