 | A QUESTION OF DATA: The Right Testing Package |
| Clients come to us at Chilworth Technology for a whole range of testing needs including data for regulatory purposes (NONS, CHIP, MSDS), transportation classification and process safety (ATEX / DSEAR). They may have one or one hundred powders to test, but in all cases they are looking for an expert assessment of their needs and a cost effective and reliable solution to their data requirements. |

 | TESTING FOR EXPLOSIVE POTENTIAL |
| Explosive substances can have a devastating impact on people and plant. Whilst we know this to be true of munitions, pyrotechnics and other “tailored” explosives, this can also be true of many other chemicals used for completely innocent, unrelated purposes. Some pharmaceuticals and fine chemicals contain highly energetic functional groups, which can impart potentially explosive properties to a molecule. |

 | STATIC ELECTRICITY & RELATIVE HUMIDITY DATASHEET |
| If static is believed or suspected to be a hazard it is crucial to understand the effect of Relative Humidity on the electrostatic properties of the material involved. Only then will it be possible to propose effective measures for the avoidance of static hazards and solving electrostatic problems. |

 | STATIC ELECTRICITY AND ATEX / DSEAR DATASHEET |
| In June 2003, it became a legal requirement throughout Europe that new and modified plant must comply with the requirements of the European Directive ATEX 137, which in the U.K. is implemented as part of the DSEAR 2002 regulations. Of all sources of ignition that must be considered under this legislation, the ATEX Directive draws explicit attention to only one – STATIC ELECTRICITY |

 | STATIC ELECTRICITY AND FIBCs DATASHEET |
| Flexible Intermediate Bulk Containers (FIBCs) are used for the storage, packaging and transportation of powders and granules in many industries. What is not always appreciated is that basic FIBCs can produce electrostatic discharges capable of igniting flammable gases, vapours and dust clouds. |

 | A Question of Compliance: ATEX / DSEAR |
| ATEX 137 was introduced as European Directive 1999/92/EC on 16th December 1999 and sets out the minimum requirements for maintaining the health and safety for the protection of workers potentially at risk from explosive atmospheres. All EU member states had to implement into national Health & Safety Regulations by no later than 30th June 2003. This was achieved in the UK by the introduction of DSEAR 2002 (Dangerous Substances and Explosive Atmospheres Regulations).

 | ATEX 95 (100a) Compliance for Equipment Manufacturers & End Users |
| Since 30th June 2003 it has been necessary for ‘End Users’ to correctly select and install electrical and non-electrical equipment into classified hazardous areas. Whether the equipment is supplied directly from an EU manufacturer or put into first use by the End User, the equipment must be in compliance with the Essential Health and Safety Requirements of ATEX 95 (100a) Directive 94/9/EC and its associated UK Regulation. |

 | COMAH / Seveso II Assessment |
| The aim of the COMAH Regulations 1999 is to prevent major accidents involving dangerous substances in the workplace and to limit the consequences of any such accidents to people and the environment. There are legally binding requirements on all sites affected by this Regulation to ensure they have a Safety Management System (SMS) in place to prevent major accidents. For sites with large quantities of dangerous substances there is also a requirement to compile a safety report, issue this to a Competent Authority and draft an on-site emergency plan. This datasheet looks at the latest changes to COMAH and how they may affect your site. |

 | DSEAR Compliance for the Food Industry |
| Many materials are handled within the Food Industry that have flammable or explosible properties but their hazards are often overlooked as they are considered ‘everyday’ products. These materials may be in either powder or liquid form and can be produced naturally or chemically. Published data indicates that the Food Industry experiences more recorded explosions than any other segment of industry with over 30% of all reported incidents involving food or animal feed.

 | DSEAR Compliance for the Utilities Industry |
| Utility companies, like those in many other industries have a duty of compliance with the safety requirements of EU Directive ATEX 137 (implemented within the UK as DSEAR 2002). The Water Industry is well aware of the fire and explosion hazards presented by flammable gases such as methane and bio-gas, but newer processes such as the drying of sewage sludge present a new dust explosion hazard. In the Power Industry, dangers associated with flammable dusts are well understood from experience with coal and coke. However, with the introduction of new bio-mass fuels the Power Industry faces additional hazards from properties such as thermal instability and the variable composition of these materials. |

 | Electrical & Non-electrical Equipment Risk Assessment |
| Since 30th June 2003 it has been necessary for ‘End User Operators’ to identify and classify hazardous areas within their plant and develop safety management systems (SMS) that allow the safe use of electrical and non-electrical equipment in these areas. They must be able to demonstrate compliance with the ATEX Directives and their associated UK Regulations, i.e. the “Dangerous Substances and Explosive Atmospheres Regulations” (DSEAR) and the EPS Regulations for equipment. |

 | EMERGENCY PRESSURE RELIEF VENT SIZING |
| An emergency pressure relief system is the most frequently employed Basis of Safety option for overpressure protection in the chemical, pharmaceutical and allied industries. It can provide protection to reactors, storage tanks, dryers and other processing equipment. However, the correct specification and operation of the emergency pressure relief system is critical for the safety of staff and the environment. |

 | FIRE SAFETY ORDER |
| The Regulatory Reform (Fire Safety) Order is the latest piece of legislation in the safety arena designed to simplify, rationalise and consolidate existing fire safety legislation in England and Wales (separate orders are to be introduced for Scotland and Northern Ireland at a later date). The existing legislation affected includes the Fire Precautions Act 1971 and the amended Fire Precautions (Workplace) Regulations 1997. There is also a general duty of care under the Health & Safety at Work Act 1974 as well as a number of more specific regulations. |

 | IEC 61508/11 & COMAH Safety Management |
| For high hazard sites, the Safety Instrumented System (SIS) is seen as a crucial layer to risk reduction and an important element of the Basis of Safety. Justification of the link between the major accident hazard and the risk reduction afforded by the Safety Integrity Level (SIL) of the intended system is an industry concern. |

 | IEC 61508/11 Functional Safety |
| If you rely on an electrical, electronic or programmable electronic system for the safety of any part of your processing operation, there is a need to verify and demonstrate the performance and integrity of the system. IEC 61508 is a generic standard on which specific industry sector safety related standards are to be based. For the process sector IEC 61511 is in preparation and like IEC 61508 outlines a preferred lifecycle for any Safety Instrumented Systems. Its international adoption provides an accepted benchmark for determining the Safety Integrity Level, design requirements and test intervals for Safety Instrumented Systems. |

 | IEC 61508/11 SIL Determination |
| In many applications dedicated instrumented trip and alarm systems are essential for plant safety. In order that we can identify a suitable Basis of Safety for a plant the functionality and reliability requirements of such instrumented safety systems need to be determined and recorded. This can be done most effectively by using the safety lifecycle strategy described within IEC 61508/11. |
