Chemical Terms
Sostanza chimica

Nome comunemente utilizzato per designare elementi chimici, composti e miscele di composti ed elementi.

Agente chimico

Questo termine è utilizzato nella normativa di base in materia di SSL: 'Chemical agent`1 means any chemical element or compound, on its own or admixed, as it occurs in the natural state or as produced, used or released, including release as waste, by any work activity, whether or not produced intentionally and whether or not placed on the market

Articolo chimico

An object which during production is given a special shape, surface or design which determines its function to a greater degree than does its chemical composition.

Esempi tipici sono pneumatici, arredi in plastica, dispositivi elettronici, tessuti prodotti con fibre chimiche, cavi.

Prodotto chimico

Prodotto costituito da una o più sostanze chimiche o composti. La sua funzione è determinata in larga misura dalla sua composizione chimica.
Esempi tipici sono colle, pitture, inchiostri, disinfettanti, biocidi, plastificanti, silicone, fuochi artificiali, oli lubrificanti, ecc.

Composto

Composto chimico formato da due o più elementi chimici.

Sostanza pericolosa

La classificazione delle sostanze pericolose si basa sulle categorie definite nella nel regolamento CLP Tali categorie comprendono i pericoli per la sicurezza (esplosivo, infiammabile, instabile, ecc.), i pericoli per la salute (tutti gli aspetti dei danni a breve e lungo termine per la salute) e i pericoli ambientali (ambiente acquatico, ecc.).

Polvere

Solid particles of a substance or mixture suspended in a gas (usually air).

Fumi

Il termine “fumi” si riferisce in particolare a particelle solide fini in sospensione nell’aria, spesso prodotte dalla volatilizzazione di sostanze fuse (ad esempio fumi di saldatura o di gomma).

Gas

Gas means a substance which: 
(i) at 50 °C has a vapour pressure greater than 300 kPa (absolute); or 
(ii) is completely gaseous at 20 °C at a standard pressure of 101,3 kPa;

Generated air contaminants - see: Generated substances
Generated substances - generated air contaminants

Substances and air contaminants may be generated from process at work places, e.g. combustion processes where fumes, exhausts and smoke is emitted and, grinding and cutting processes emitting dust. These generated substances and air contaminants may be dangerous.

Hazardous substance - see ‘Dangerous substance’

A substance which fulfils the criteria relating to physical hazards, health hazards or environmental hazards, laid down in Parts 2 to 5 of Annex I of the CLP Regulation, and classified in relation to the respective hazard classes provided for in that Annex.

The classification of dangerous substances is based on categories defined in the CLP Directive. These categories include physical hazards (explosive, flammable, instable etc.) health hazards (all aspects of short and long term harm to health) and environmental hazards (aquatic
environment etc.) 
Often hazardous substances and dangerous substances are used like synonyms. There is no clear distinction, language preferences play a role.

Liquido

Liquid means a substance or mixture which: 
(i) at 50 °C has a vapour pressure of not more than 300 kPa (3 bar);
(ii) is not completely gaseous at 20 °C and at a standard pressure of 101,3 kPa; and 
(iii) which has a melting point or initial melting point of 20 °C or less at a standard  pressure of 101,3 kPa;

Miscela

‘Mixture’ means a mixture or solution composed of two or more substances.

Generato da un processo

I contaminanti generati da un processo possono essere generati come emissioni da qualsiasi tipo di processo che comporta un’esposizione negli ambienti di lavoro, ad esempio processi di combustione, processi che determinano una degradazione fisica o chimica del materiale di partenza o che lo modificano in altro modo.

Solido

Solid means a substance or mixture which does not meet the definitions of liquid or gas (CLP)

Stato della materia caratterizzato da rigidità strutturale e da resistenza a variazioni di forma o volume.

Sostanza

‘Substance’ means a chemical element and its compounds in the natural state or obtained by any manufacturing process, including any additive necessary to preserve its stability and any impurity deriving from the process used, but excluding any solvent which may be separated without affecting the stability of the substance or changing its composition;
Elemento chimico o composto formato da due o più elementi chimici.

Health and Safety
Cancerogeno

Carcinogen means a substance or a mixture of substances which induce cancer or increase its incidence.

Esplosivo

An explosive substance or mixture is a solid or liquid substance or mixture of substances which is in itself capable by chemical reaction of producing gas at such a temperature and pressure and at such a speed as to cause damage to the surroundings.

Esposizione

Il termine “esposizione” indica che una sostanza è presente nell’ambiente di un lavoratore e può essere inalata o assorbita per contatto con la pelle (compresi gli occhi, le orecchie) o mediante ingestione. Contact of an organism with a chemical, radiological, or physical agent. Exposure is quantified as the amount of the agent available at the exchange boundaries of the organism (e.g. skin, lungs, gut) and available for absorption.

Infiammabile

Il regolamento CLP stabilisce una differenziazione tra gas infiammabili, aerosol infiammabili, liquidi infiammabili e solidi infiammabili e applica criteri diversi. Una definizione semplificata è che tutte le sostanze che possono prendere fuoco e bruciare o alimentare l’accensione e la combustione di altri materiali sono classificate come infiammabili.

Hazard

A hazard is anything that has the potential to cause harm. Hazards can affect people, property, processes; they can cause accidents and ill-heath, loss of output, damage to machinery, etc. 

Ingestione

Introduzione di alimenti, farmaci, liquidi o altre sostanze nel corpo attraverso la bocca.

Inalazione

Inspirazione d’aria nelle vie aeree e nei polmoni.

Irritanti, della pelle

Skin irritation means the production of reversible damage to the skin following the application of a test substance for up to 4 hours.

Mutageno

A mutation means a permanent change in the amount or structure of the genetic material in a cell. The term ‘mutation’ applies both to heritable genetic changes that may be manifested at the phenotypic level and to the underlying DNA modifications when known (including specific base pair changes and chromosomal translocations).

Tossicità per la riproduzione

Reproductive toxicity includes adverse effects on sexual function and fertility in adult males and females, as well as developmental toxicity in the offspring.

Risk

Occupational risk refers to the likelihood and the severity of an injury or an illness occurring as a result of exposure to a hazard. 

Sostanze sensibilizzanti, delle vie respiratorie e della pelle

Respiratory sensitiser means a substance that will lead to hypersensitivity of the airways following inhalation of the substance.

Skin sensitiser means a substance that will lead to an allergic response following skin contact

Sensitising

Respiratory sensitiser means a substance that will lead to hypersensitivity of the airways following inhalation of the substance.

Skin sensitiser means a substance that will lead to an allergic response following skin contact

Tossicità (acuta)

Dal punto di vista giuridico, una sostanza chimica (sostanza, miscela) presenta tossicità acuta se soddisfa i seguenti criteri stabiliti dal regolamento CLP:

Acute toxicity means those adverse effects occurring following oral or dermal administration of a single dose of a substance or a mixture, or multiple doses given within 24 hours, or an inhalation exposure of 4 hours.

Il regolamento CLP distingue tra tossicità per via orale (ingestione), tossicità per via cutanea (contatto) e tossicità per inalazione.

Tossicità (altro)

L’esposizione a sostanze pericolose può causare danni a organi specifici. Il regolamento CLP stabilisce una differenziazione dei danni a organi specifici tra danni dovuti a un’esposizione singola e danni dovuti a esposizioni ripetute.

Indicazione di pericolo

Hazard statement means a phrase assigned to a hazard class and category that describes the nature of the hazards of a hazardous substance or mixture, including, where appropriate, the degree of hazard;

Measurement of air contaminants

Measurement of the concentration of air contaminants at the workplace. Measurements may be used for measuring workers´ exposure or to study the concentration of air contaminants at the workplace, e.g. leakages, identification of sources emitting air contaminants and evaluation of the effectiveness of local exhausts as a basis for decisions about what measures should be taken. Depending on which substance is to be measured, different kinds of measuring equipment are available. 

Misurazione

Misurazione dell’esposizione dei lavoratori a sostanze chimiche pericolose mediante l’utilizzo di metodi e strumenti di misura specifici per la sostanza/il gruppo di sostanze. Sono molto utilizzate la misurazione di concentrazioni aeree nei luoghi di lavoro (permanente e caso per caso) e la misurazione di sostanze pericolose o dei loro metaboliti nelle sostanze biologiche (ad es. sangue o urina) del lavoratore o dei lavoratori esposti.

Measures - Control Measures

All measures that aim at increasing safety and health. Measures may either reduce the generation of dangerous substances or reduce the risk of exposure. 

Misure organizzative

Tutte le misure volte alla riduzione delle esposizioni a sostanze pericolose mediante interventi sull’organizzazione (ad es. riduzione del numero di lavoratori nelle aree esposte).
