EXTREME DANGER WARNING

Phosgene (COCl₂) is one of the most lethal chemical warfare agents ever used. Even brief exposure to low concentrations can be fatal. Immediate detection is critical for survival.

  • Lethal Concentration: 50 ppm for 30 minutes = death
  • Delayed Effect: Symptoms may not appear for hours
  • No Antidote: Only supportive treatment available

The Phosgene Threat

Understanding the deadliest chemical warfare agent and its insidious nature.

Chemical Warfare History

Phosgene was first used as a chemical weapon in World War I, where it killed more soldiers than any other chemical agent. Despite being banned under the Chemical Weapons Convention, the threat remains due to its dual-use nature as an industrial chemical and potential for terrorist deployment.

The insidious nature of phosgene poisoning - with a "latent period" where victims feel well before sudden onset of fatal pulmonary edema - makes early detection absolutely critical for survival.

Phosgene Properties

Formula COCl₂
Odor Sweet hay-like (low concentrations)
Density 3.4 × heavier than air
Boiling Point 8.2°C
Persistence Non-persistent (disperses quickly)

⚠️ Warning: Odor threshold is above dangerous levels

Health Effects & Medical Emergency

Understanding the deadly progression of phosgene poisoning and critical exposure levels.

Acute Exposure Symptoms

Phase 1: Immediate (0-4 hours)

  • Mild eye and throat irritation
  • Slight coughing
  • Chest tightness
  • DANGER: Symptoms may be minimal

Phase 2: Latent Period (4-24 hours)

  • FALSE RECOVERY: Victim feels better
  • Symptoms may completely disappear
  • Cellular damage continues silently

Phase 3: Pulmonary Edema (6-72 hours)

  • LIFE-THREATENING: Lungs fill with fluid
  • Severe breathing difficulties
  • Pink, frothy sputum
  • Cardiovascular collapse
  • Death from respiratory failure

Toxicity Levels

Exposure Level Effect
0.1 ppm Odor threshold (unreliable)
0.4 ppm Immediate danger threshold
2 ppm Maximum for 1 hour
4 ppm Dangerous after 30 minutes
50 ppm Fatal in 30 minutes
100+ ppm Rapidly fatal

⚠️ CRITICAL: No safe exposure level established
