What happens when you inhale phosphine gas?

Acute (short-term) inhalation exposure to phosphine may cause headaches, dizziness, fatigue, drowsiness, burning substernal pain, nausea, vomiting, cough, labored breathing, chest tightness, pulmonary irritation, pulmonary edema, and tremors in humans.

What is the DOT Hazard Class and zone for phosphine?

Chemical Identifiers

NIOSH Pocket Guide International Chem Safety Card

What is the RQ for phosphine?

SARA Title III Status (Section 302 (40CFR355), Section 311/312, Section 313 (40CFR372)): 40CFR355 lists phosphine as an Extremely Hazardous Substance with a Threshold Planning Quantity (TPQ) of 227 kg (500 lbs.) and a Reportable Quantity (RQ) of 45.4 kg (100 lb).

Can we breathe phosphine?

Inhaling phosphine causes respiratory irritation, compromises heart (cardiac) and circulatory functions, depresses the central nervous system, and produces severe gastrointestinal pain. EYE EXPOSURE: Ocular exposure to phosphine gas has not been known to cause systemic toxicity.

How long does phosphine gas last?

Phosphine in the atmosphere is rapidly degraded (World Health Organization, 1988). The half-life in air is approximately five hours with the mechanism of degradation being photoreaction with hydroxy radicals. The dark half-life is approximately 28 hours.

Can someone survive phosphine gas?

Conclusions: Unintentional phosphine gas exposure is rare but has a toxic profile that results in a high fatality rate with no known antidote.

What hazard class is phosphorus?

Hazard Class: 4.1 4.1
UN Number: UN1338 UN1338
Packing Group: III III

Is acetone listed in Appendix A?

For example, Acetone, a Class 3 flammable liquid material is listed in Table 1 to Appendix A, and may meet the definition of a hazardous substance. Review section 171.8 for more information on the definition of a hazardous substance.

What is the TPQ for bromine?

500 lbs
Bromine is an extremely hazardous substance (EHS) subject to reporting requirements when stored in amounts in excess of its threshold planning quantity (TPQ) of 500 lbs. 40 CFR 355 (USEPA); U.S. National Archives and Records Administration’s Electronic Code of Federal Regulations.

Does phosphine mean life?

There is phosphine in the atmospheres of Jupiter and Saturn, for example, but there it is not a sign of life. Scientists think it is formed in the deep atmosphere at high pressures and temperatures, then dredged into the upper atmosphere by a strong convection current.

How is phosphine related to life?

As far as we know, on rocky planets such as Venus and Earth, phosphine can only be made by life—whether human or microbe. Used as a chemical weapon during World War I, phosphine is still manufactured as an agricultural fumigant, is used in the semiconductor industry, and is a nasty byproduct of meth labs.

Where is phosphine gas found?

In the outer solar system, phosphine is made deep in the interiors of Jupiter and Saturn. Near the giant planets’ cores, the temperatures and pressures are extreme enough to craft the molecule, which then rises through the atmosphere.

Is the smell of phosphine harmful to humans?

Phosphine is a colorless gas with an odor that has been described, by various observers, as similar to that of garlic, rotting fish or stale urine. As exposure deadens the sense of smell, do not use smell to determine phosphine concentration. Phosphine’s immediate health hazards are that it is a toxic gas and may cause thermal burns.

When did phosphine safety data sheet p-4643 come out?

Phosphine Safety Data Sheet P-4643 This SDS conforms to U.S. Code of Federal Regulations 29 CFR 1910.1200, Hazard Communication. Date of issue: 01/01/1980 Revision date: 08/31/2018 Supersedes: 10/24/2016

What is the CAS number for phosphine hydride?

Name : Phosphine CAS No : 7803-51-2 Formula : PH3 Other means of identification : Hydrogen phosphide, Phosphorous hydride, Phosphorous trihydride, Phosphorated hydrogen 1.2. Relevant identified uses of the substance or mixture and uses advised against Use of the substance/mixture : Industrial use. Use as directed. 1.3.

How is phosphine stable at room temp?

Chemical Stability: Phosphine is stable at room temperature. At elevated temperature (above 150 deg. C), phosphine decomposes to phosphorus and hydrogen. Diphosphine may also result from thermal decomposition. Conditions to Avoid: Temperatures above 55 deg. C, sources of ignition, exposure to air.
