Forest fires cause numerous social and environmental impacts in Brazil and worldwide. Implementing safety curtains prevents the spread of a fire and helps in firefighting techniques. Thus, the aim of this research was to evaluate the flammability of Caatinga plants and their efficiency as safety curtains to prevent forest fires in the Paraíba semiarid. This research was developed in the field and in the laboratory. In the field, burning occurred in 1 m2 experimental plots containing 2 kg of cacti, hardwood fuel material and pine needles, in which the thickness and volume of the blanket, material humidity, frequency and ignition time, burning time, flame height, propagation speed, fire intensity, combustibility and severity index, temperature of combustible material and soil were determined. In the laboratory, the ash content and the higher calorific value were determined. The species cacti (Opuntia sp, Cereus jamacaru, Pilosocereus gounellei) showed longer ignition times and shorter combustion times, being burned only the thorns. The specie Cnidoscolus quercifolius did not differ from cacti in their burning time. The specie Aspidosperma pyrifolium and the Cenostigma bracteosumpresented moderately higher severity index due to the high calorific value of the wood. Cacti and C. quercifolius presented lower calorific power, being recommended for use in safety curtains. Aspidosperma pyrifolium and Cenostigma bracteosumshowed differences in flammability between the constituent parts of the plants, not being recommended as safety curtains. ; Os incêndios florestais causam inúmeros impactos socioambientais no Brasil e no mundo. A implantação de cortinas de segurança impede a propagação de um incêndio na propriedade e auxilia nas técnicas de combate. Assim, objetivou-se nesta pesquisa, avaliar a inflamabilidade de plantas da Caatinga e sua eficiência como cortinas de segurança na prevenção de incêndios florestais no semiárido paraibano. A pesquisa foi desenvolvida em campo e em laboratório. Em campo, a queima ocorreu em ... |
