Evaluate a substance using the COSHH Essentials method (high-level wrapper)

Chains coshh_grade(), coshh_classify_volatility() (if applicable), coshh_risk() and coshh_measures() to produce a complete result row from the raw data of a substance. Designed to be called directly from code (scripts, reports, purrr::pmap, vignettes) without going through the Shiny application.

Usage

coshh_evaluate(
  name,
  phrases,
  quantity,
  is_liquid,
  boiling_point = NA_real_,
  process_temp = NA_real_,
  dustiness = NA_character_
)

Arguments

name: Character. Identifying name of the substance.
phrases: Character. H/R phrases; see coshh_grade().
quantity: Character. Quantity class in the active language.
is_liquid: Logical. TRUE if the substance is liquid (volatility will be calculated from boiling_point / process_temp); FALSE if solid (dustiness will be used directly).
boiling_point, process_temp: Numeric. Required only if is_liquid = TRUE. See coshh_classify_volatility().
dustiness: Character. Required only if is_liquid = FALSE. Dustiness class in the active language.

Value

A one-row data.frame with columns substance, phrases, grade, volatility, quantity, risk and measures.

Details

Output labels (volatility class, quantity class, control measures) are returned in the active language; see expoquimr_lang().

Examples

coshh_evaluate(
  name = "Toluene",
  phrases = "H315, H336",
  quantity = "Medium",
  is_liquid = TRUE,
  boiling_point = 111,
  process_temp = 20
)
