Convenience and Safety Options

Stairway:

9.3Replace paragraph 9.3 with the fol- lowing: A 30" wide, 45° steel stairway with 8" rise and run, shall be provided at the tower endwall rising from grade (roof) to the fan deck elevation. Stair treads shall be bar grating with checker plate nosing, and shall be through bolted to structural channel string- ers. Stairway posts, guardrails and toeboards shall be as specified per Paragraph 9.2. Structural steel sup- port columns for the stairway shall be provided by the cooling tower manu- facturer. Stairway foundation shall be by others, designed in accordance with drawings provided by the cooling tower manufacturer. The entire stairway shall be hot-dip galvanized after fabrication and shall conform to OSHA standards.

Plenum Walkway:

9.1Add the following to the end of this paragraph: Provide a 30" wide bar grat- ing walkway extending from one endwall access door to the other in each cell.This walkway shall be supported by a galva- nized steel framework, and the top of the grating shall be above the cold water basin overflow level. If the cold water basin is deeper than 4'-0", the walkway shall be equipped with guardrails.

Ladder Extension:

9.4Add the following paragraph in the Access and Safety section: Provide a ladder extension for connection to the base of the ladder attached to the tower casing. This extension shall be long enough to rise from the roof (grade) level to the base of the tower. Anchorage and lateral bracing of the ladder extension shall be by others.

Ladder Safety Cage:

9.3Add the following to the end of this paragraph: A heavy gauge galvanized steel safety cage shall surround the ladder, extending from a point approxi- mately 7'-0" above the base of the ladder to the top of the guardrail sur- rounding the fan deck.

Specification Value

Although they are not necessary for routine operation and mainte- nance, stairways do provide a safe and comfortable means of access to the top of the tower that is often overlooked in the initial cooling tower purchase. They are designed in straight-run or double-back configura- tions to accommodate your site requirements.

This option permits freedom of movement for inspection or mainte- nance within the tower without the need for wading boots or tower drainage. It also helps prevent maintenance personnel from damag- ing submerged accessories in the cold water basin (such as screens, probes, basin heaters, etc.).

Many towers are installed such that the base of the tower is 2'-0" or more above the roof or grade level. This makes it difficult to get up to the base of the attached ladder. The ladder extension alleviates this problem. Marley ladder extensions are available in standard 5'-0" and 11'-0" lengths, and will be field-cut to fit.

To meet OSHA guidelines, towers whose fan

decks are 20'-0" or more above roof or grade, and which are equipped with ladders, are required to have safety cages surrounding the ladders.
