Demolition Methods, Sanitation Networks, and Safety Plans

Development and Implementation of Demolition

1. Dismantling of industrial equipment.
2. Demolition or removal of bodies and covered ledges.
3. Demolition or removal of the deck.
4. Demolition of elements at each plant: interior partition walls, curtain walls, and cargo.
5. Demolition of structural elements: forged with beams, reinforced concrete slabs (one-direction, two-directions), beams, brackets, domes.

Types of Demolition

According to Procedure

1. Element by element.
2. With collapse.
3. Mixed or combined.

According to Media

1. Manual.
2. Mechanical.
3. Thermal.
4. By explosives.

Design of a Sanitation Network

• If the network is public: Mixed.
• If two networks (wastewater and stormwater): Separator system.

Basic Sanitation Network Requirements

1. Dispose of water seal to prevent the passage of air.
2. Simple piping layout.
3. Appropriate diameter.
4. Network accessible for maintenance.
5. Have ventilation systems.
6. Must not discharge waste other than stormwater or wastewater.

Considerations in Sanitation Network

Tightness and movement of the network.

Types of Evidence in Sanitation Network

• Partial Sealing: Downloading every single device, emptying tests in each section of pipe, manholes, and wells.
• Total Seal: A lump sum or in parts.

All with air, water, or smoke.

Characteristics of Small Evacuation Network

• Length of siphoning boat to the downpipe: <2m.
• Derivations rushing the siphonic boat: <2.5 m with slope 2-4%.
• Individual siphon devices.
• Overflows in toilets, bidets, bathtubs, and sinks.

Qualities Required of a Pool

• Lightweight
• Impervious to wind, rain, or snow
• Cohesion between materials
• Fireproof
• Impact resistance
• Mechanical strength
• Resistance to acid fumes/industrial

Tests to be Done to a Pool

Tightness of risk simulated deck. It's rejected if there is penetration within 48 hours after the test.

Difference Between ESS and PSS

ESS (Estudio de Seguridad y Salud - Health and Safety Study)

1. Forms part of the implementation and should be consistent with it.
2. Used to build CSS projects or project phases.
3. Collects anticipated risks and adequate preventive measures.
4. Contains information about safety and health for future action.
5. Includes a budget to quantify projected costs, feeding into the general budget of the work as an additional chapter.

PSS (Plan de Seguridad y Salud - Health and Safety Plan)

1. Developed by the contractor; estimates discussed in the ESS, and the PSS is produced as the actual implementation of the ESS.
2. Must be approved before the start of the work by the Health and Safety Coordinator (HSC).
3. Subject to continual changes during the development of the work.
4. Carries the same documentation as the ESS planning, complemented by a security force and recommendations.

Types of Hydraulic Seals

• Individual siphon
• Siphon boat
• Chest drain trap
