Identification of Substance

SUBSTANCES

(a)Mortar

(b)Screed

YORKSHIRE MORTAR & SCREED LTD, SMEATON INDUSTRIAL PARK WENT EDGE ROAD , WENTBRIDGE,PONTEFRACT WF8 3LU

Composition

Mortar & screed is a mixture of natural aggregates, cementitous material including cement and water together with admixtures and colourings, the resultant mixture is abrasive and alkaline

Hazards identification

(a)Wet mortar & screed

Contact with wet mortar & screed can cause;

1.Irritant contact dermatitis

2.Allergic contact dermatitis

3.Cement burn

(b) Mortar & Screed dust

Cutting and surface treatment of hardened concrete can create dust and flying fragments, the dust created could contain particles of a respirable size which may contain silica. When the dust contains silica, the risks are increased. Extended periods of exposure to hich concentrations of such dust can be hazardous to health

 First Aid Measures

(a)Skin Contact

Immediately wash with copious amounts of water. Remove contaminated clothing. Seek Medical Attention

(b)Eye Contact

Immediately irrigate with copious amounts of water. Seek Medical Attention

(c)Ingestion

Remove from exposure to fresh air. Seek Medical Attention

Mortar & Screed Dust

(a)Inhalation

Remove from Exposure to air

(b) Skin Contact

Wash with Water

(c)Eye Contact

Immediately irrigate with copious amounts of water Seek Medical Attention

(d)Ingestion

Remove from exposure to air

Accidental Release Measures

(a)Personal Protection

Avoid skin and eye contact. Wear protective equipment as specified in Personal Protection.

(b)Environmental Measures

Prevent entry in to drains and water courses.

(c)Method of Cleaning

To avoid hardening, recover as quickly as possible in the wet or semi dry state .Water spray to avoid the creation of airborne dust. Avoid skin contact.

Handling & Storage

(a)Wet Mortar & Screed Dust

Avoid skin and eye contact.

(b)Mortar and Screed Dust

Cutting a surface treatment of hardened concrete should be worked to minimise the creation of airborne dust. Engineering control measures such as containment and local exhaust ventilation should be applied when airborne dust levels are approached.

Toxiological Information

Health Effects

(a)Wet Mortar & Screed Dust

Eyes: May cause irritation and in severe cases alkali burns.

Skin: Short term contact may cause alkali burns. Prolonged contact may cause both irritant and contact dermatitis.

(b)Mortar & Screed Dust

On Eyes: May cause transient irritation.

On Skin: Unlikely to cause harm on brief or occasional Contact.

By Inhalation: Inhalation of large quantities of respirable silica may lead to progressive lung damage. This may cause permanent disability and, in extreme cases, may be fatal.

By Ingestion: Unlikely to cause harm.

Chronic: Exposure to high levels of silica may cause progressive silicosis.

Others: None Known
