My Flashcards

Definition

Meaning

A device for measuring the concentration of explosive gases or vapors in the air.

A portable instrument used primarily in mining, chemical industries, and safety inspections to detect and quantify the presence of flammable atmospheres to prevent explosions.

Linguistics

Semantic Notes

The term is highly specific to industrial safety and occupational health contexts. It is a compound of 'explosi-' (from explosive) and '-meter' (measuring device). It refers to the instrument itself, not the person using it.

Dialectal Variation

British vs American Usage

Differences

No significant spelling or usage differences. The term is equally rare in both varieties.

Connotations

Purely technical, with strong associations to mining safety, petrochemical plants, and hazardous environment monitoring.

Frequency

Extremely low-frequency term in general discourse. Used almost exclusively by safety engineers, inspectors, and professionals in high-risk industries.

Examples

By CEFR Level

A2
  • The miner carried a special device for safety.
B1
  • Before entering the tank, the worker checked the air with a meter.
B2
  • Safety protocol requires the use of an explosimeter to test for flammable vapors in confined spaces.
C1
  • The readings from the newly calibrated explosimeter indicated a methane concentration well below the lower explosive limit.

Learning

Memory Aids

Mnemonic

Think: EXPLOSIve + meter (like thermometer) = EXPLOSIMETER, a meter for explosive stuff.

Conceptual Metaphor

A CANARY IN A COAL MINE (modern, technological version).

Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

  • Avoid literal translation or creation of a similar-sounding Russicism. Use established technical translations like 'газоанализатор' or 'взрывомер' only in precise contexts.

Common Mistakes

  • Confusing it with a 'smoke detector' or 'fire alarm'. Using it as a verb (e.g., 'to explosimeter').

FAQ

Frequently Asked Questions

An explosimeter is a specific type of gas detector designed to measure concentrations of flammable or explosive gases, typically displaying the reading as a percentage of the Lower Explosive Limit (LEL).

They are used by safety engineers, miners, firefighters, chemical plant operators, and anyone working in environments where explosive atmospheres may form.

Typically, no. A standard explosimeter is calibrated for flammability, not toxicity. Multi-gas detectors combine these functions.

No, it is a very low-frequency technical term unknown to the general public but standard within specific industrial safety fields.
