SECTION 8 : EXPOSURE CONTROLS/ INDIVIDUALS
8.1 Control parameters
Exposures limits (France): dust limits for innocuous effect:
Total dust: VME : 10 mg/m3
Alveolar dust: VME : 5 mg/m3
Calcium Dihydroxide: VME : 5 mg/m3
Recommendations of the Scientific Committee for Occupational Exposure (SCOEL [1])
Natural Hydraulic lime (NHL):
Acute effect: DNEL : 4 mg/m3 (breathable dust)
Long term effect: DNEL : 1 mg/m3 (breathable dust)
This value is cross referenced to Natural Hydraulic Lime in view of the anticipated equivalent local effect (pH is comparable to that of CaO and Ca(OH)2).
8.2 Exposure Controls
To control potential risks, avoid generating dust.
Wear protective equipment. Eyes protection equipment (goggles or visors for example) are necessary unless contact with the eyes is avoided by the nature and type of application (closed process for example). In any case protection of the face, protective clothing and safety shoes must be worn.
Refer to the Exposure Scenario annex available.
8.2.1 Appropriate technical controls
If the product application generates dust, use enclosures, local ventilation or other technical methods to maintain dust limits below the maximum recommended.
8.2.2 Individual protection measures and personal protective equipment
8.2.2.1 Eyes and face protection
Do not wear contact lenses.
Wear tight fitting goggles with side shields or large vision full goggles.
It is also recommended to carry an eyewash.
8.2.2.2 Skin protection
As NHLs are classified as irritant for the skin, dermal exposure has to be reduced to the minimum as much as possible.
Wear protective rubber gloves (nitrile rubber with minimum failure > 480) conforming with Directive 89/686 and to the corresponding Standard EN 374.
Wear protective clothes offering total protection for the skin (long trousers , long sleeves, close fitting at openings) and shoes resistant to caustic products.

SECTION 10 : STABILITY AND REACTIVITY
10.1 Reactivity
In aqueous media Ca(OH)2 disassociates, forming Calcium cations and hydroxyl anions (when below the water solubility limit).
10.2 Chemical stability
The product is stable at ambient temperature and within the normal application and storing conditions.
10.3 Possibility of dangerous reactions
The substance produces an exothermic reaction in contact with acids.
Heated above 580oC, the Calcium dihydroxide decomposes producing Calcium Oxide (CaO) quick lime
and water (H2O): Ca(OH)2 –> CaO + H2O. The Calcium Oxide reacts with the water and generate heat.
This could be a risk in the presence of flammable materials.
10.4 Conditions to be avoided
Minimise exposure to air and humidity to avoid degradation.
10.5 Incompatible materials
NHLs produce an exothermic reaction in contact with acids to form salts.
In presence of humidity the NHLs react with aluminium and brass producing hydrogen Ca(OH)2 + 2Al + 6H2O –> Ca[Al(OH)4]2 + 3 H2
10.6 Hazardous decomposition products
None to our knowledge.
Complementary information: Calcium dihydroxide reacts with Carbon dioxide forming Calcium Carbonate which is a natural occurring material.
SECTION 11 : TOXICOLOGICAL INFORMATION
11.1 Information on toxicological effects
NHL are classified as irritant for the skin, respiratory ways and present a risk of serious eyes damage.
The limit of exposure to prevent sensorial local irritation and the parameters of critical effects for the lungs is OEL ou VLEP (8h) = 1 mg / m3 of breathable dust.
Acute toxicity:
None observed. A study on acute skin toxicity and inhalation effects has been considered scientifically not necessary.
Oral : DL50 > 2000 mg/kg (OCDE 425, substance tested Ca(OH)2,rat). By cross reference these results are applicable to NHLs.
Dermal: not available
Inhalation: not available For respiratory irritation see below.
Skin corrosion/irritation
Calcium Dihydroxide is irritant for the skin. By cross reference this result is applicable to NHLs. On the basis of experimental tests on similar substances the NHLs are classified as irritant for the skin [skin Corrosion/Irritation, category 2 (H315- Cause skin irritation / R38, irritant for the skin)].
Serious eyes damage/irritation Calcium Dihydroxide has a risk of causing serious eyes damage (live studies in vivo, rabbit). By cross reference these results are applicable to NHLs.
On the basis of experimental tests on similar substances the NHLs are classified as severe irritants for the eyes [serious eyes damage/irritation category 1 (H318 – Causes serious eye damage/R41 Risk of serious eye damage)].
Respiratory Irritation
On the bases of studies on Calcium Oxide and Dihydroxide, by cross reference NHLs are classified as Irritant for the respiratory ways.[Toxicity specific to target organs-single exposure category (H335 –can cause irritation of respiratory ways / R37 – Irritant for the respiratory system)].
Respiratory or skin sensitisation
No data available.
Bases upon the known effects (pH modification) and on the basic human need for calcium in food, NHLs are considered as not producing a sensitisation effect to the skin. None of its components are known to have a sensitisation effect (ie: calcium carbonate calcium silicate and calcined clay mineral). The definition “sensitising” is not justified.
Germ cells mutagenicity
Bacterial reverse mutation tests (Ca(OH)2 and CaO, Tests d’Ames, OCDE 471) : negative.
Mammalian chromosome aberration test [Ca(OH)2]: negative.
By cross reference these results are applicable to NHLs.
None of the components of NHLs is known as genotoxic.
Considering the pH effect, there is no mutagenicity.
The definition “genotoxic” is not justifiable.
Carcinogenicity
Calcium (administered as Ca-lactate) is not carcinogenic (experimental result rat).
The pH effect does not present a carcinogenic risk.
The definition “carcinogenic” is not justifiable.
Reproductive toxicity
Calcium (administered as Ca-carbonate) is not toxic to reproduction (experimental studies on mice). The pH effect does not present a risk to reproduction.
Clinical studies on humans and animals with different calcium slats have not shown ant effect on reproduction or developmental.
NHLs are not toxic for reproduction or development.
The definition “ toxic to reproduction” conforming to Regulation (CE)1272/2008 is not justified.
Specific toxicity for target organs (STOT)-single exposure
Calcium dihydroxide does not have specific toxicity for any exposure medium (dermal, oral, inhalation).
Specific toxicity for target organs (STOT)-repeated exposure
The toxicity of Calcium ingested is specified by the maximum tolerable limit (UL) for adults:
UL = 2500 mg of Ca corresponding to 36 mg of Ca per kg of body weight for an adult weighing 70kg
(Data from CSAH: Comité Scientifique en matière d’Alimentation Humaine).
The toxicity of NHLs by skin absorption is not considered pertinent due to its insignificant absorption and the primary effect of local irritation (effect pH).
The toxicity due to inhalation (localised effects, mucous irritation) due to the CaO and the Ca(OH)2 is determined by SCOEL (Scientific Committee on exposure levels) as follows: DNEL = 1 mg / m3; breathable dust (see section 8.1) and VLEP (8h) = 1 mg / m3.
The definition “toxic after repeated exposure” is not justified.
Hazards due to ingestion
Ingesting large quantity causes burns in the mouth, oesophagus, digestive track, nausea and vomit.
