Fire shutters

Protection at non-personnel opening moy consist of overheod fire shutter, horizontal sliding fire door or other rated fire door assemblies that are listed for opening protection. 

Certain types and layouts of doorways, windows, infill panels and fixed or openable glazed areas may be covered by a building code. It may include, for example, distances between windows on either side of a fire wall, and where protection of the opening is required internal or external wall-wetting sprinklers, or automatic fire doors for doorways, automatic fire shutters for windows or construction of approved FRL for other openings.

Active fire protection are measures to contain the spread of fire which require some form of mechanical actuation, i.e. operation of smoke vents or release of fire shutters. 

Active systems also include those that assist in compartmenting the fire such as fire door release mechanisms, fire shutters and mechanical damping systems. In addition other systems may be actively used for smoke extraction.

E-beam is a relatively cold process and so is more suitable for heat-sensitive substrates. UV lamps emit about one third UV light and the rest is visible and IR. Consequently substrates can get very hot, even causing fires if they become stuck beneath the lamp. Safety shutters which close if the line stops are installed on many UV bulbs. 

Acceptance testing of fusible link fire dampers should always include a random sample actual fusible link (melting) test of the installed assembly that causes the damper to close. Many times an improperly installed damper will not close correctly and the shutter louvers become hung up or twisted. An alternative sometimes available is a link assembly that can be temporary installed that is easily cut by a pair of clippers. The fusible link melting temperature can then be tested separately at a convenient location without subjecting the installation heat or flames for testing purposes.

The films can be grown by various methods (see Section 3.6.9). G.H. Haertling and G.C. Robinson [10] describe the production of 6 /nn thick (9/65/35) PLZT films on sapphire substrates by an automated repeated dipping/firing process. The dipping solution consisted of the acetates of the metal ions, La, Zr, Ti and Pb. The films were the basis of a successful shutter and display based on the principles described above (see Sections 8.21 and 8.33). 

The laboratory was cold and dark. It never used to be, but now it was. I went to the window and flung back the shutters one after another until the room was revealed in all its complicated vastness. Then I sank down on the window seat. Everything was wrong. The laboratory had been the hub of my universe, its wheels turned by fire and water, the instruction of our notebooks, the recording of our processes. I had indexed and labeled its contents myself because my father, fanatical about order and economy, depended on being able to put his hand on a book, a substance, a crucible the instant he needed it. And every instrument had to be maintained to a perfect level of utility scales balanced, chisels polished, irons scrubbed clear of rust, chemicals redated and replenished. Even while the hedges on our land were broken and our roses mildewed, our laboratory had remained airy, well oiled, constant. But now the room was furred by a kind of violent neglect. 

A burst of laughter penetrated from the library and a carriage rolled away outside, followed by the squeal of our msty gates. What with the fire and the furnace, the warm night, and too much wine, I felt stifled, so I opened a high central flap in the shutters. The moon had come out and its white face, squashed like a grapefmit, shone directly onto the cloud of vapor collected in the receiver. There it was, exposed. Palingenesis. 

There were great changes here. The shutters had been repaired and nailed into place, the furnace cleaned, and a fire laid. My father s workbench was in its old position, the top planed smooth and polished, his staff propped against it. Even more intriguing was that some form of experiment had been set up a long tube of metal from what looked like a gun barrel had been bent into an S shape, one end of which was connected to a retort, the other to an inverted flask.

Many of the workers on the eighth floor were able to squeeze through the doorway and found refuge either on the street or, after that passageway had been cut off, on the roof. Others crowded into the two elevators which ferried dangerously heavy loads to safety. Those who climbed on to the fire escape, however, found that the narrow, flimsy structure was blocked by an open shutter locked into place. As more and more women piled on to it the structure buckled from the heat and collapsed, sending dozens of workers to their death eight stories below. Most of those on the tenth floor were able to escape either to the roof or by one of the elevators, which made its first stop for the executives. It... 

The three little pigs were smart. As the winds whipped against their shutters, they ran from the house of straw and the house of sticks. The pigs then ran to the house of bricks and built a fire in the fireplace. Today, the fires are burning in organizations. They are calling for a redesign of the supply chains. 

The local fire department must be well acquainted with your facility, its location, and specific hazards. The fire alarm system mnst be certified, as required, and tested at least annually. Interior standpipes must be inspected regularly. Outside private fire hydrants must be flushed at least once a year and on a routine preventive maintenance schedule. All fire doors and shutters must be in good operating condition, unobstructed, and protected against obstructions, including their counterweights.
