The CDM (Construction and Design Management regulations 2015) Q2. What can be defined as an opening to a suspended slab? A. Any structure which is temporarily supported or requires parts of the structure to be fully or partially removed such as holes, gaps, voids and any area which lead to a person falling. Q3. What should be done prior to cutting openings and once they have been cut? A. A full inspection of the area and isolation to anyone entering the area should be created prior to starting the works. During and after the works are completed any access and egress should remain in place if still suspended or if openings and gaps remain. Plywood sheeting should be used to cover opening left, this should be secured.

Safe Working Zones DS14:Temporary Works – Supporting Structures • The only positive method for securing a cut piece in a wall opening is by strapping. Strapping is a method in which a metal plate or angle iron (or unistrut) is attached to both the opening and the remaining wall section by drop-in or wedge-type anchors. Ask these to confirm understanding: Q1. What can be classed as a Temporary Works structure or work? A. Falsework, supporting structures of any type, cutting opening and any load needing to be propped, stored or controlled during a cutting or breaking out process. Q2. What two items should be used to support and control the cutting of a concrete opening? A. Strapping to hold the load from falling and drop-in or wedge type anchors.

Use 2400 Kilograms per 1000mm3 (1 meter cubed) depending on the density and type. Q2. What is the main factor that has to be considered for concrete weight when lifting the item? A. Do we know the weight of the load and the lifting capacity of the crane/hoist and the lifting equipment capability before we commence the lift or movement of the load. Q3.

Guidance Notes GN1:Floor Saw Blade Bolts and Latch Plate - Husqvarna TechTips SB FS Latch 0721 Floor Saw Latch Plates It has come to our notice that many operators do not appreciate the importance of the latch plate on the blade guard of a floor saw. On floor saws the latch plate is a safety precaution so that if the operator has left the blade bolt (or nut) loose, the plate will reduce the chance of a slack bolt (nut) and outer flange from separating from the machine. On some models, the latch plate has a second function, on those machines the latch plate bridges the two halves of the blade guard and ensures the two halves of the guard cannot part whilst in use. We recommend that floor saw operators are instructed prior to using the machine to ensure the correct blade bolt and washer is fitted, the blade bolt is tightened and the latch plate is fitted, the floor saw should not be used if the latch plate is damaged and not to use the saw without the latch plate engaged and the securing bolt installed at all times. All floor saws in hire fleets should be inspected before going out on hire to ensure the latch plate is in place and in an operational condition.
