                           Improvement 
                            notices are concerned with requiring a duty holder 
                            to make certain specified changes to the workplace 
                            within a specified period of time.  
                          Section 
                            21 of the Health and Safety at Work Act states that: 
                             
                          
                             
                              | "If 
                                an inspector is of the opinion that a person  |

                              is 
                                contravening one or more of the relevant statutory 
                                provisions; or  |

                                circumstances that make it likely that the contravention 
                                will continue or be repeated,  |

                                may serve on him a notice (in this Part referred 
                                to as "an improvement notice") stating 
                                that he is of that opinion, specifying the provision 
                                or provisions as to which he is of that opinion, 
                                giving particulars of the reasons why he is of 
                                that opinion, and requiring that person to remedy 
                                the contravention or, as the case may be, the 
                                matters occasioning it within such period (ending 
                                not earlier than the period within which an appeal 
                                against the notice can be brought under section 
                                24) as may be specified in the notice. " | 
                             
                           
                            
                            HSE's Enforcement Guide states that:  
                           
                            "An 
                              improvement notice should be used in situations 
                              which can be remedied within the period specified. 
                              They cannot be used to require an obligation which 
                              has no attainable end, e.g. a notice might require 
                              the provision of a guard but cannot require that 
                              it be maintained in good condition. A notice can 
                              properly require that, by a given date, there should 
                              be in place a system for maintenance, as this is 
                              a requirement to remedy the matters that led to 
                              the breach. 
                            When 
                              notices concerning "systems" are served 
                              there should, as with the serving of all notices 
                              whenever possible, be a discussion with the duty 
                              holder as to steps to be taken to comply and an 
                              effort to resolve points of difference."  
                           
                          It 
                            should be noted that the circumstances that require 
                            an improvement notice to be imposed, are the same 
                            ones that could result in a prosecution. It is therefore 
                            important that an inspector determines whether or 
                            not an improvement not
