Sulphuric acid as a corrosive poison. the characteristics, fatal dose, fatal time, sign and symptoms, post-mortem appearance and medicolegal importance are discussed
12. CAUSES OF DEATH
• Circulatory collapse
• Spasm or edema of glottis
• Collapse due to perforation of stomach
• Toxaemia
• Delayed death may occur due to hypostatic
pneumonia, secondary infection, renal infection or
starvation due to stricture of esophagus
13. • Depends on quantity, strength, duration of the acid exposed
• Corrosion of mucous membranes of lips, mouth and throat and
skin over chin, angles of the mouths and hands
• Necrotic areas; 1st grayish white, but soon become brown or black
and leathery
• Chalky white teeth
14. Internal
• Limited to upper digestive tract and respiratory system
• Upper digestive tract; inflamed, swollen, severe
interstitial haemorrhage
• Esophagus: superficial mucosa erosion
• Stomach: superficial erosion and coagulation with
eschar
• Soft, spongy, black mass which readily disintegrates
when touched. Mucosal ridges damaged

Notas del editor
SO3 fumes escape and combine with moisture in the air to form sulfuric acid mist particles that are visible and can create clouds of dense, white fumes.
Brown or dark in color (commercial H2SO4)
Excoriated=damage or remove part of the surface of (the skin)
Immediate burning pain
Eructation=burping=release of gas from the digestive tract (mainly esophagus and stomach) through the mouth.
hypostatic pneumonia: pneumonia that usually results from the collection of fluid in the dorsal region of the lungs and occurs especially in those (as the bedridden or elderly) confined to a supine position for extended periods
