The concept of a dose-response relationship by using a specific chemical

Prepare a Power Point presentation summarizing three related items below:

1. The concept of a dose-response relationship by using a specific chemical, physical and/or biological hazard (that you select and research). Based on your chemical, find the corresponding Threshold Limit Values (TLV), Permissible Exposure Limit (PEL) and Recommended Exposure Level (REL) which sets the daily amount a worker could be exposed to the chemical. Note the three values are provided by three different bodies. Summarize in the PowerPoint slide the following for your chemical:

a. Route(s) of entry e.g. inhalation, absorption, ingestion and injection. Specify which the primary is.

b. Locate and find the Lethal dose or lethal concentration of this chemical based on CDC studies and the TOXNET data base using the United States National Library of Medicine (NLM) Toxicology Data Network http://toxnet.nlm.nih.gov/ and Centers for Disease Control (CDC) http://www.cdc.gov/.. Summarize the doses and how study was conducted.

c. Provide the specific TLV, REL and PEL for chemical. Explain the difference and the agency/body who provided the limits.

(Note this could be a few as three slides with great precision.)

 

2. Locate an Occupational Health Surveillance program for one of OSHA’s regulated chemicals contained in 29 CFR 1910 Subpart Z. Summarize the mandatory medical surveillance requirements for workers exposed above the action level set for the chemical.

(NOTE: Do not make this overly complicated. Find a hazard chemical and find the medical protocols. Prepare one or two slides to summarize the requirements. )

3. Indoor Air Quality Standards – Given there are no specific regulated standards, there are however, several established indicators for using CO2 as an indicator of poor indoor air quality. Read chapter 15 and locate specific guidance on CO2 Levels and the agency/body/group etc. that provides this guidance. Summarize the Indoor Air Quality CO2 guidance thresholds on a PowerPoint slide and explain why CO2 can be used as an indicator of poor indoor air quality.
