Chemical Agents: Tetraethyl Lead
Chemical Agents
Choose a specific chemical from the list of chemicals provided in the .pdf file entitled ‘Ontario OELs’ found on eClass under Assignment 1. Do NOT choose gasoline, benzene, diesel, or any chemical that is described as a solid at room temperature. To randomize the assignment for the class, you must choose a chemical whose name starts with the same letter as the first letter of your last name (* see exceptions below). You must investigate and report on the chemical, only using the headers and subheaders in shown here below in bold text: Chemical name: List your chemical’s name, and its CAS Number [CAS no.] Hazardous physical/chemical properties: Describe the basic properties and those that contribute to make your chemical hazardous to humans. Provide specific data from your sources, and explain in plain language. You must link together the provided data and your related comments about hazards. Routes of entry: Describe the routes of entry of your chemical into the body (link each route to the expected ‘states’ of the chemical). Effects on the body: Describe the effects on the human body. Sources of exposure: What Industries and/or processes use this chemical? Control Measures: Describe the measures required to safely control your chemical in the workplace, beginning with Pre-contact controls: {Engineering, Policy & Procedure, Administration, and PPE} and concluding with Post-contact controls: {First Aid, Fire Fighting and Accidental Release] measures}. Remember, you must use these subheaders. SDS (SDS) Attach a copy of one (1) complete SDS along with your Assignment (else 1-mark deduction). In your SDS, your chemical must have at least 80% concentration. Bibliography:- Must cite at least 5 sources from the Internet, including ONLY 1 SDS- Do not use other sources (textbooks, notes, magazines).- Must use MLA or APA style for internet citation
Its either 825 words with with 2.5 pages of information and 1 page for a completed safety data sheet (SDS). Safety data sheets arent really filled with too many words but are a page. If not, then 2 pages of information and the safety data sheet (SDS).

Chemical Name: Tetraethyl lead (CAS no.) 78-00-2
Hazardous Physical/Chemical Properties
The chemical is liquid with no color but can be dyed with blue, orange, or red colors, it smells pleasantly sweet. It boils at 392 degrees Fahrenheit, freezes at -202 degrees Fahrenheit, and with a 200 degrees’ Fahrenheit flash point. Also, the chemical has a specific gravity of 1.65 and a molecular weight of 323.45. The chemical has a heavier vapor than air and has a chemical risk of decomposing once heated. The chemical reacts aggressively to strong oxidants, halogens, and acids generating the risk of fire and explosions (Sarkar, 2020). Further, Tetraethyl lead has environmental hazards as it affects aquatic organisms because it destabilizes the aquatic environment.
Routes of Entry
The chemical has three routes of entry to human health that is, ingestion, dermal exposure, and inhalation. The chemical is an organic lead that is distributed to the brain and metabolized to Tetraethyl lead upon exposure through any route (Sarkar, 2020). Tetraethyl lead can last months in the body as it is slowly metabolized to an inorganic lead that will deposit in the bones.
Effects on the Body
The chemical has differing effects depending on the route of exposure. For dermal exposure, the chemical is absorbed through the skin causing itchiness, burning feeling, and redness, it may also cause the skin to look pale. In case of inhalation exposure, tetraethyl lead may cause sneezing, irritating the upper respiratory tract, and systemic effects such as; anxiety, nausea, headaches blurred speech, or euphoria. Last, ingestion exposure would cause nausea, vomiting diarrhea, and an increase in intracranial pressure and pulmonary edema (Odenbro, 2020). The chemical has severe long-term effects on the body such as interfering with the central nervous system and making the human reproductive and development processes toxic.
Sources of Exposure
Tetraethyl lead (TEL) is exposed to the environment through fumes from car exhaust after being used as an automotive gasoline, at least 1% of the content is expelled without being exchanged (Serih et al., 2022). Tel can also evaporate from gas tanks and stations and in case the chemical spills accidentally.
Control Measures
Pre-Contact Controls
1 Engineering controls help reduce the chance of exposure thus involving having local exhaust ventilation systems and isolating TEL handling and storage areas.
2 Administration measures
Assessing potential risk hazards before handling the chemical.
Safety storage in airtight and well-designed containers that cannot leak or spill
Create an emergency communication plan in case of accidents and train all the persons on how to handle TEL responsibly
3 Personal protective equipment (PPE) Give directives for using appropriate PPE such as gloves, respiratory protectors, lab coats, and safety goggles. The PPE should be inspected regularly and thoroughly and replaced when needed.
Post Contact Controls
1 First-aid measures
If inhaled, expose the victim to fresh air take a rest, and refer for further medication.
After a dermal exposure, remove the contaminated clothes, then rinse and wash the skin with water and soap. Al...
