What are the physical hazards associated with reactives?


What are the physical hazards associated with reactives?

Explosive materials can suddenly, almost instantaneously, release pressure, gas and heat when subjected to sudden shock, pressure or high temperature. Other materials may become dangerous when mixed with water, air or other chemicals.

What hazards make up the flame pictogram?

What are the hazards of products that have a flame pictogram?

  • a source of fuel (e.g., the flammable product),
  • oxygen, and.
  • heat (e.g., an ignition source such as a spark).

What are the hazards of naphthalene?

repeated exposure can cause clouding of the eye lens (cataract), which may damage vision. ► Inhaling Naphthalene can irritate the nose and throat. ► High exposure to Naphthalene can cause headache, fatigue, confusion, tremor, nausea and vomiting.

Is ethylene oxide safe for humans?

Ethylene oxide (C₂H₄O) is a flammable gas with a somewhat sweet odor. Exposure to ethylene oxide may cause headache, nausea, vomiting, diarrhea, breathing difficulty, drowsiness, weakness, exhaustion, eye and skin burns, frostbite, and reproductive effects. Workers may be harmed from exposure to ethylene oxide.

Is reactives a physical hazard category?

Physical hazard means a chemical for which there is scientifically valid evidence that it is a combustible liquid, a compressed gas, explosive, flammable, an organic peroxide, an oxidizer, pyrophoric, unstable (reactive) or water-reactive.

What are fire hazards?

Fire hazards are workplace hazards that either involve the presence of a flame, increase the probability that an uncontrolled fire will occur, or increase the severity of a fire should one occur. Fire hazards include: Flames. Sparks. Hot objects.

Which pictogram causes severe skin burns and damage to the eyes?

The exclamation mark pictogram is used for the following classes and categories: Acute toxicity – Oral, Dermal, Inhalation (Category 4) Skin corrosion/irritation – Skin irritation (Category 2) Serious eye damage/eye irritation – Eye irritation (Category 2 and 2A)

Is naphthalene poisonous to humans?

Naphthalene is used in the production of phthalic anhydride; it is also used in mothballs. Acute (short- term) exposure of humans to naphthalene by inhalation, ingestion, and dermal contact is associated with hemolytic anemia, damage to the liver, and neurological damage.

Is the smell of mothballs harmful to babies?

Storing treasured baby clothes in mothballs can be lethal, say leading pediatricians from Australia and New Zealand. The doctors say the fumes could lead to severe brain damage in babies and even death from the insecticide naphthalene used in mothballs.

Is ethylene oxide a carcinogenic?

The National Institute for Occupational Safety and Health (NIOSH) recommends that ethylene oxide be regarded in the workplace as a potential occupational carcinogen, and that appropriate controls be used to reduce worker exposure.

Is ETO sterilization banned?

25, 2019 — In 2005, the U.S. Environmental Protection Agency considered banning ethylene oxide in new sterilizing facilities because of the cancer risk it posed to residents who lived around the plants.

Is flammability a physical hazard?

Physical hazard are based on the intrinsic properties of the chemical. There are five main classes of physical hazard namely Explosive, Flammable, Oxidising, Gases under Pressure and Corrosive to metals.
