Concepts

This case-sensitive code system `http://terminology.hl7.org/v2plusvocab/CodeSystem/risks` defines the following codes:

Code | Display | Definition | versionIntroduced | usage
AGG | Aggressive | Aggressive | 2.5 | A danger that can be associated with certain living subjects, including humans.
BHZ | Biohazard | Biohazard | 2.5 | Material contains microorganisms that are an environmental hazard. Must be handled with special care.
BIO | Biological | Biological | 2.5 | The dangers associated with normal biological materials. I.e. potential risk of unknown infections. Routine biological materials from living subjects.
COR | Corrosive | Corrosive | 2.5 | Material is corrosive and may cause severe injury to skin, mucous membranes and eyes. Avoid any unprotected contact.
ESC | Escape Risk | Escape Risk | 2.5 | The entity is at risk for escaping from containment or control.
EXP | Explosive | Explosive | 2.5 | Material is an explosive mixture. Keep away from fire, sparks, and heat.
IFL | MaterialDangerInflammable | MaterialDangerInflammable | 2.5 | Material is highly inflammable and in certain mixtures (with air) may lead to explosions. Keep away from fire, sparks and excessive heat.
INF | MaterialDangerInfectious | MaterialDangerInfectious | 2.5 | Material known to be infectious with human pathogenic microorganisms. Those who handle this material must take precautions for their protection.
INJ | Injury Hazard | Injury Hazard | 2.5 | Material is solid and sharp (e.g., cannulas.) Dispose in hard container.
POI | Poison | Poison | 2.5 | Material is poisonous to humans and/or animals. Special care must be taken to avoid incorporation, even of small amounts.
RAD | Radioactive | Radioactive | 2.5 | Material is a source for ionizing radiation and must be handled with special care to avoid injury of those who handle it and to avoid environmental hazards.
