following chemical agents are to be considered dangerous within the meaning regulations:

explosive substances and preparations: solid, liquid, pasty or gelatinous and preparations which may also react exothermically without oxygen thereby quickly evolving gases, and which, under defined test detonate, quickly deflagrate or upon heating explode when partially oxidising substances and preparations: substances and preparations which a highly exothermic reaction in contact with other substances, flammable substances;

(c) extremely flammable substances and preparations: liquid preparations having an extremely low flash-point and a low boiling-point gaseous substances and preparations which are flammable in contact ambient temperature and pressure.

(d) highly flammable substances and preparations: - substances and preparations which may become hot and fire in contact with air at ambient temperature without any of energy, or - solid substances and preparations which may readily catch brief contact with a source of ignition and which continue be consumed after removal of the source of ignition, or - liquid substances and preparations having a very low flash-point, - substances and preparations which, in contact with water evolve extremely flammable gases in dangerous quantities;

(e) flammable substances and preparations: liquid substances and having a low flash-point;

(f) very toxic substances and preparations: substances and preparations in very low quantities cause death or acute or chronic damage to inhaled, swallowed or absorbed via the skin;

(g) toxic substances and preparations: substances and preparations quantities cause death or acute or chronic damage to health when inhaled, or absorbed via the skin;

(h) harmful substances and preparations: substances and preparations may cause death or acute or chronic damage to health when inhaled, absorbed via the skin;

(i) corrosive substances and preparations: substances and preparations may, on contact with living tissues, destroy them;

(j) irritant substances and preparations: non-corrosive substances preparations which, through immediate, prolonged or repeated contact or mucous membrane, may cause inflammation;

(k) sensitising substances and preparations: substances and preparations if they are inhaled or if they penetrate the skin, are capable of eliciting hypersensitisation such that on further exposure to the substance of characteristic adverse effects are produced;

(l) carcinogenic substances and preparations: substances or preparations if they are inhaled or ingested or if they penetrate the skin, may induce increase its incidence;

(m) mutagenic substances and preparations: substances and preparations if they are inhaled or ingested or if they penetrate the skin, may induce genetic defects or increase their incidence;

(n) substances and preparations which are toxic for reproduction: and preparations which, if they are inhaled or ingested or if they penetrate may produce, or increase the incidence of, non-heritable adverse progeny and/or an impairment of male or female reproductive functions SCHEDULE V Substituted by: L.N. 353 of 2007; L.N. 53 of 2012; L.N.57 of 2018; L.N. 356 of 2021.
