Let an agent handle toxicity by substance, dose, endpoint and route, give poison centre and emergency contacts first in exposures, and give no guidance on harming anyone.

Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent handle toxicity by substance, dose, endpoint and route, give poison centre and emergency contacts first in exposures, and give no guidance on harming anyone.

The degree to which a substance can harm an organism, depending on dose, route and duration of exposure; specific forms include organ toxicity such as hepatotoxicity and nephrotoxicity.

What it is for: Assessing hazards to protect health and the environment.

It can be read safety data sheets; call a poison centre after an exposure; assess risk in regulation; monitor drug side effects with clinicians.

Distinguishing features

Dose makes the poison

Acute and chronic

Organ-specific forms

Classified under GHS

What it looks like

Not visible; expressed as dose-response data and hazard classifications.

Physical character

acute oral toxicity category 1: LD50 up to 5 mg/kg - GHS classification

How it is recognised

Hazard pictograms such as skull and crossbones

Values such as LD50 or NOAEL

Organ toxicities named by organ

Exposure Emergency first.

Exposures need help fast.

Emergency

Poison centre.

Emergency

Emergency response.

  1. Has someone been exposed, and should a poison centre or emergency service be called now? boundary
  2. What information will they ask for? action

First aid

Safety data sheet.

  2. What must not be done? boundary
Hazard Classification.

Classification communicates hazard.

Class

GHS.

Class

Hazard class.

  1. How is the substance classified? provenance
  2. What pictograms and statements apply? definition

Data

Dose-response.

Data

Toxicity data.

  1. What toxicity values are reported? measurement
  2. From which study or database? provenance
Medicine Drug toxicity.

Clinicians monitor toxicity.

Monitoring

Tests.

Monitoring

Monitoring.

  1. Does this medicine need monitoring for organ toxicity? boundary
  2. Who should the patient ask? action

Reporting

Side effects.

Reporting

Adverse event reporting.

  1. How can a suspected side effect be reported? action
  2. To which regulator? provenance
Prevention Safe use.

Prevention avoids harm.

Storage

Child safety.

Storage

Safe storage.

  2. Is child-resistant packaging used? boundary

Workplace

Exposure limits.

Workplace

Exposure limits.

  1. What occupational exposure limits apply? measurement
  2. What protection is required? boundary

What the second pass must settle

  • Should organ toxicities be separate entries?
  • How should poison centre contacts be localised?
  • How should toxicity data be linked?
