4. First aid measures    
     
     
Eye contact : Can cause significant eye irritation. If product gets into eyes,
      check for and remove any contact lenses. Hold eyelids apart and
      flush  immediately  with  plenty  of  clean  water  for  at  least  10
      minutes.  Seek  medical  attention  if  symptoms  persist  or  are
      severe.
     
Skin contact : If skin contact occurs, remove contaminated clothing and shoes
      and then flush skin with mild soap and water. Clean contaminated
      shoes and clothing before re-use. If skin irritation occurs and is
      persistent, contact a doctor/physician.
     
Inhalation : If product is inhaled and breathing is difficult, remove exposed
      person from contaminated area to fresh air. Keep the person
      warm and at rest. If the person is not breathing, if their breathing
      is  irregular  or  if  respiratory  arrest  occurs,  provide  artificial
      respiration or oxygen by trained personnel. Maintain an open
      airway.  Loosen  tight  clothing  such  as  a  collar,  tie,  belt  or
      waistband. Contact physician urgently
     
Ingestion : If swallowed, rinse mouth with water.  Remove dentures if any.
      Move exposed person to fresh air. Keep exposed person warm
      and  at  rest.  If  the  exposed  person  is  conscious,  give  small
      quantities of water to drink. If vomiting occurs, the head should
      be kept low so that vomit does not enter the lungs. Get medical
      attention if symptoms persist.
Protection of First-Aiders   If first aiders are required to enter dust exposure area, respiratory
      and other PPE must be used.
Notes to physician : No specific treatment.  Treat symptomatically. Contact a poison
      treatment specialist immediately, if large quantities are ingested
      or inhaled.
       

Aluminium Silicate

  1. Fire-fighting measures
Suitable extinguishing media : Use an extinguishing media appropriate for fine particles that
    may arise from the material.
     
Special exposure hazards : The  product  is  a  non-flammable  solid.  Any  fine  suspended
arising from substance or   particles  of  dust  could  have  the  potential  to  form  explosive
preparation   mixtures with air. If there is a fire, promptly isolate the scene by
    removing all persons form the vicinity of the incident. No action
    shall be taken involving any personal risk or without suitable
    training.
     
Hazardous thermal : Inadequate data available
decomposition products    
Special protective equipment : Appropriate protective equipment and SCBA with a full face-
for fire-fighters   piece operated in positive pressure mode should be worn.
     
  1. Accidental release measures
Personal precautions : No action shall be taken involving any personal risk or without
    suitable training. Do not touch or walk through spilled material.
    Use suitable protective equipment and prevent the generation of
    dust where possible.  Wear respiratory protection equipment to
    avoid breathing dust. Remove product from ignition sources as
    all fine powders can be combustible. See Section 8.
     
Environmental precautions : Avoid dispersal of spilled product and limit contact with soil,
    waterways, drains and sewers as far as practically possible.
    Ensure  contaminated  run  offs  are  dealt  with  appropriately,
    according  to  approved  environmental  management  plans.  If
    possible, vacuum dry spillages, alternatively wet spilled material
    with water to reduce dust generation before and during handling.
    Avoid dust generating and handling operations where possible.
    See Section 13.
     
Cleaning up methods : Small spill: Vacuum or sweep up spilled product and place in an
    appropriately designated and labelled container. If disposal is
    required, this must be undertaken in accordance with local laws
    and regulations.
  :  
    Large spill: Contain product to limit the potential to enter sewers,
    water courses, basements or confined areas. Trained personnel
    can vacuum or sweep up material and place in appropriately
    designated and labelled containers.  If disposal is required, this
    must  be  undertaken  in  accordance  with  local  laws  and
    regulations.  Note:  see  Section  1  for  emergency  contact
    information and Section 13 for waste disposal.
  : Uncontaminated product can be re-used after careful cleaning.
    Any resulting  solid  waste  that  cannot  be  re-used  should  be
    Page 4 of 11
Version 1   Date of Issue: 04 September 2017

Aluminium Silicate disposed of according to the local laws and regulations. Also see Directive 2008/50/EC.

  1. Handling and storage of bulk material
Handling : Wash  face,  hands  and  forearms  thoroughly  after  handling
    product. Avoid dust generating activities where possible and use
    filters and exhaust ventilation to reduce dust, especially when
    crushing.   In  the  interests  of  good  industrial  hygiene,  wear
    appropriate personal protective equipment as informed by an
    occupational  health risk  assessment.  Maintain  a  clean  work
    place to prevent dust accumulation. Recycle all waste where
    possible. If product becomes contaminated, dispose of according
    to the local laws and regulations.
     
Storage : Store in an area away from incompatible materials and ignition
    sources. Store separately from water, acids and any oxidizing
    agents. In powder form, store in 1 ton bulk bags sealed to avoid
    dust dispersal. Ensure containers are adequately labelled.  Use
    appropriate containment to avoid environmental contamination.
     
Packaging & Transport: : Conventional bulk handling techniques should be used when
    packaging  and  transporting  the  product.  Product  should  be
    covered during transport as far as possible.
