That Tank had Cl2 (Chlorine Gas) in it.

Also known as Mustard Gas in WWI.

NASTY $}{!T !!! When I was working in Water Treatment I was changing a 2000 lb Tank and the new one had a leaky valve on the packing of the valve stem. As soon as I started to open the valve I saw it start leaking and immediately turned the valve back to the closed position. I got just a minimal nose sniff of it in an open air environment and it was enough to cause breathing, sight problems and several hours of major discomfort from it. Bleeding nose, burning lungs, runny eyes. I never want to go through that again !!!

EXPOSURE
AVOID ALL CONTACT!
IN ALL CASES CONSULT A DOCTOR!
Inhalation
Cough. Sore throat. Shortness of breath. Wheezing. Labored breathing. Symptoms may be delayed. See Notes.
Use breathing protection, closed system or ventilation.
Fresh air, rest. Half-upright position. Refer immediately for medical attention. Artificial respiration may be needed. See Notes.
Skin
ON CONTACT WITH LIQUID: FROSTBITE. Redness. Burning sensation. Pain. Skin burns.
Cold-insulating gloves. Protective clothing.
First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. Refer immediately for medical attention.
Eyes
Watering of the eyes. Redness. Pain. Burns.
Wear face shield or eye protection in combination with breathing protection.
Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer immediately for medical attention.
Ingestion
Do not eat, drink, or smoke during work.

General measures
Material Safety Data Sheet Product Name: Chlorine
: DANGER: Oxidizing gas. Corrosive. Evacuate personnel to a safe area.
Wear a self-contained breathing apparatus and appropriate personal protective equipment (PPE).
Approach suspected leak area with caution. Remove all sources of ignition. Toxic, corrosive vapor can spread from spill. Contact with flammable materials may cause fire or explosion. Ventilate area or move container to a well-ventilated area. Before entering the area, especially a confined area, check the atmosphere with an appropriate device. Prevent from entering sewers, basements and work pits, or any place where its accumulation can be dangerous.
SECTION 7: Handling and Storage
Precautions for safe handling
: Do not breathe gas/vapor. Avoid all contact with skin, eyes, or clothing.
Emergency eye wash fountains and safety showers should be available in the immediate vicinity of any potential exposure Wear leather safety gloves and safety shoes when handling cylinders. Protect cylinders from physical damage; do not drag, roll, slide or drop. While moving cylinder, always keep in place removable valve cover. Never attempt to lift a cylinder by its cap; the cap is intended solely to protect the valve. When moving cylinders, even for short distances, use a cart (trolley, hand truck, etc.) designed to transport cylinders. Never insert an object (e.g, wrench, screwdriver, pry bar) into cap openings; doing so may damage the valve and cause a leak. Use an adjustable strap wrench to remove over-tight or rusted caps. Slowly open the valve. If the valve is hard to open, discontinue use and contact your supplier. Close the container valve after each use; keep closed even when empty. Never apply flame or localized heat directly to any part of the container. High temperatures may damage the container and could cause the pressure relief device to fail prematurely, venting the container contents
SECTION 8: Exposure Controls/Personal Protection:
TLV-TWA (ppm) 0.5 ppm TLV-STEL (ppm) 1 ppm
: Wear safety glasses with side shields. Wear goggles and a face shield when trans filling or Breaking transfer connections. Provide readily accessible eye wash stations and safety
