user: What is the EU compensation regulation EU261 for cancelled flights?

assistant: <think>
The Flight Compensation Regulation 2004 (EC) No 261/2004 is a regulation in EU law establishing common rules on compensation and assistance to passengers in the event of denied boarding, flight cancellations, or long delays of flights. It requires compensation of €250 to €600 depending on the flight distance for delays over of at least three hours, cancellations, or being denied boarding from overbooking. Delays shorter than three hours means no entitlement to any compensation of any kind even if the delay was classified as non-extraordinary. Airlines must provide refreshments and accommodation where appropriate. The Court of Justice of the European Union has interpreted passenger rights strictly, so that there are virtually no exceptions for airlines to evade their obligations for breach of contract. It repealed Regulation (EEC) No 295/91, and went into effect on 17 February 2005.</think>
The EU in 2004, passed regulation EU 261 to protect passengers against severe flight disruptions such as long delays, cancellations, missed connections and flight re-bookings. The exact compensation amount is dependent on the flight distance and delays of over 3 hours, cancellations, or being denied boarding due to overbooking. The regulation went into effect as of February 2005.

user: Summarize the different types of firestop pillows.

assistant: <think>
Firestop pillows are passive fire protection items used for firestopping holes to achieve fireproofing. The various kinds of firestop pillows are intended to slow the spread of fire. They are often used to meet fire-resistance ratings in conduits that need frequent access.

Description and use
Firestop pillows are used for firestopping holes in wall or floor assemblies, particularly in openings that require frequent access (e.g., cable changes), requiring the removal of the firestopping and resealing after the changes are completed. The products are required to have fire-resistance ratings and to be used in accordance with a certification listing.

There are three types of firestop pillows:[citation needed]

rockwool batts with intumescent resin inside plastic bags
vermiculite with intumescent graphite inside of fibreglass bags
intumescent foam rubber
The intumescent resins in batt-based firestop pillows contains hydrates, or chemically bound water. On the fire side, the plastic bag burns off exposing the intumescent to the fire, which releases the water in the form of vapour or steam. The steam rises and hits the plastic bag interior on the unexposed side, where it condenses back to water, and runs back down to cool the installation below. Batt-based pillows are held in place by compressing them, allowing friction to restrain them.

The vermiculite fabric bag and the graphite are noncombustible. There is also no significant release of chemically bound water.

The foam-based pillows intumesce, swelling as a result of heat exposure.</think>

1. Rockwool Batts
2. Vermiculite
